Your valve seals look fine to me. I'm betting you have valve stem clearance problems with the guides. More than likely the guides were knurled during the last rebuild which is kind of a band aid. It's just a guess, but from your description that's what I would expect to find.

Good Luck,

Kevin

Back years ago, we used to have porous block problems with Cadillacs. It was a similar situation to what you are describing. I would recommend a retouque on the head bolts and adding some GM coolant sealing tabs if the leak persists. I have used them more times than I can remember with very good res...

I would agree on an issue with the float.

X2 on the Gray Sealer. I use a thin layer on all cork gaskets, thin like almost translucent. Also as mentioned above, make sure that the pan rails are as flat as you can make them. Pay special attention around the bolt holes. When tightening, you just want the bolts snug, not tight. If you get them ...

Soaking the bolts with any of the oils/solvents mentioned above will certainly help. If you do happen to break one of the bolts, I would not recommend trying to drill it out or use a bolt extractor with the head on the car unless it is your absolute last choice. Welding a nut to the broken bolt has ...

I would also check your wheel bearings while you are there to make sure they are evenly torqued left to right

I have generally had good luck with CJPP. What you have to keep in mind is the free shipping business model that they use, particularly on over sized parts. I am sure if you called and cancelled the order they would be cool. I would just make sure what your total cost would be including shipping fro...

I am guessing that you are working on the 67 Mustang in your signature line. I replaced the steel lines on our early 65 Mustang and used the regular carbon steel lines from NPD. They all required a little adjustment to fit but were a much easier starting point than trying to bend straight tube. The ...

ags290

All of the above sources are good suggestions. I would also add to check with some of the local machine shops and Mustang specialty shops like Colorado Mustang Specialist in Aurora. If you are patient you can watch craigslist for a while an one will show up. Most people are uninformed and consider t...

Where are you located? Someone from the forum may be able to help you locate one.

ags290

Nice Work Sir! A little lifter tick on a fresh motor startup is not uncommon, I was always told " If they are clicking, they are not burning" The main thing is no more heinous squeal! Get her broken in and enjoy!

It's looking good! I agree with cutting the heads off of a couple of old head bolts to use as guide studs when installing the cylinder head. I used two of the ones from your old 200 when putting the head on Garrett's car. I am guessing that you are using a modern composite gasket instead of the stee...

ags290

It looks like progress is being made! Good luck on the install. Did you go with a new cam as well or just pistons/rings and bearings?

ags290

And here are your bearings:

Here is what I found online. I hope it helps.

Super Cool!

ags290

Which machine shop did you end up going with? Is that a BSA uniform I see? My son with the Mustang is an Eagle Scout. I'm glad to see you making this minor set back a family affair. I hope y'all make some great memories working on the Comet together.

Chris,

How is the build coming?

I have been using Delo 400 in a 15w40 with a ZDDP additive. I don't know that the 15w40 is necessary but it has worked well for me. I think it is more important to change it more frequently. I have been changing mine every 3 months the way we all used to do it. It's cheap insurance.

X2 on getting your vacuum from the intake log.

ags290

I'm glad you were able to fish it out without having to pull the cylinder head. It's a bummer you still are having noise issues.

ags290

Thanks Bubba! It is now mine.

ags290

I am about to replace the turn signal switch in our early 1965 Mustang for the third time. The car was originally equipped with a generator so it is the same part number as the 62-64 Falcon, C30Z-13341-B. All three have been replaced for different reasons: The first was for a broken cancelling cam, ...

Mine goes to a drilled hole in the exhaust flange at the exhaust manifold as pictured below.

ags290

Those springs will be fine.

ags290

- If I upgrade to a v8 rear end/axle. Will the 6 cyl leaf springs that I purchased be ok to use to get the old saggy ones out of there, or do I have to use v8 leaf springs with a v8 rear end??? It depends on which springs you bought. There isn't really a six cylinder leaf spring from what I can tell...

Welcome Aboard, As wsa111 stated the spindles are the same on a 67-68 6 cylinder and 8 cylinder. If it were mine I would do a direct swap on the rear differential assembly from a 67 or 68 mustang. I would also do the front disc conversion using parts intended for a 67-68 mustang. The reason behind t...

I just saw a set of .040 NOS Fomoco pistons on Ebay for $125.00. I know your builder is recommending .020 but these are cool and cheap!

Howdy Y'all I just had the 170 head reworked at Arlington Automotive Machine. Their website is pretty basic but it is: https://www.arlingtonautomotivemachineshop.com They are a family run business and do great work at a fair price. They were willing to let me supply my own parts and looked through a...

ags290

What sizes are you looking for? Are they boring the block and turning the crank? Enginetech is here in Dallas and they sell kits. http://www.enginetech.com Have you looked on Rock Auto and tried to piece together what you need? Here is a kit on ebay that will at least let you see who manufactures wh...

Congratulations on winning the goods!

ags290

I'm glad it was what you thought and it sounds like you are about to be on the road again!

ags290

Let me know when you head that way next time. I would enjoy putting a face with a forum name and checking out your tri power setup and the rest of the car.

ags290

I am guessing that you have an automatic transmission since you mention one foot on the brake and the smooth shifting. All of the idle concerns started immediately after the transmission repair correct? Did the transmission shop do the install or did you just have them bench build the unit and you i...

ags290

Congratulations on the fix! Which show are you going to this weekend? Is it the cars and coffee in Plano?

ags290

The heater has worked well since the second air purge. No issues today. The boy drove her about 35 miles without issue, just lots of smiles. The key was getting all of the air out of the system. I got it to burp once on the initial coolant fill but there was still air in the system. Running the heat...

He may be able to get by with 10 lbs pressure for quite a while without issue. When I was in College I worked at a local independent parts house and we actually carried a line of oil pressure switches that wouldn't turn the idiot lights on until they registered below 5 lbs. We used to sell a lot of ...

ags290

Seth,

I am running a 190 degree thermostat and I do have the heater lines run the way they were from the factory. I believe it is a Stant or Motorcraft thermostat. What would you recommend as a good one?

Kevin

ags290

Found the leak! My son was dying to drive the car. He hadn't driven it since leaving for College after Christmas break. I figured we couldn't hurt anything so I said lets go, just in the neighborhood. We backed out of the driveway and went to accelerate and there was no 1-2 shift. Ah Ha! Turns out I...

ags290

Bubba, Thanks for the reply. I have the plugs gapped at .035, I reset the timing at 12 degrees and have a Petronix points conversion, with these settings it runs better, but not right. I am wondering if I could have a vacuum leak from either the base of the carb or the base of the spacer. I put fres...

ags290

Thanks for the advice guys, I just came back in from running the car without the radiator cap and as soon as the t-stat opened I got some more air out of the system. The temp gauge never went above the half way point and when the t-stat opened it settled in at about one quarter on the gauge even aft...

ags290

Howdy , I was setting the timing on the 170 this morning after installing the new head and noticed the temperature starting to climb. The heater hoses were warm to the touch after about 10 minutes at idle. The upper radiator hose was cold, so I grabbed my infrared temp gun and checked them. The heat...

ags290

I'm sorry you are having so much trouble. Your Comet is too cool of a car not to get back on the road before spring weather gets away from you. Reach out if you need any hard parts. I have a couple of 170 parts motors, and some miscellaneous gaskets. Good Luck!

Kevin

ags290

The head is back on she fired right up. There is a intermittent "skip" at idle that I need to figure out but hopefully the heavy lifting is over for a while. I ran it for about 30 minutes, made sure the coolant burped and we didnt have any leaks and quit for the day. I will go back and ret...

ags290

I hate to hear that. Sorry fella

ags290

WSA111,

RTV just on the threads correct?

Kevin

ags290

Did the crank show any signs of wear? Did you check the rod bearings?

ags290

Yes the head is going on the 170. I had it milled .030 and ended up with 50cc combustion chambers. I am using a Ford upper end gasket kit, C90Z-6079-A.

ags290

You might want to add some marvel mystery oil or automatic transmission fluid to your flush oil. Either of the two may help unstick your rings and clean out the sludge. Just don't go crazy driving the car with either one in the crankcase. The milkshake sludge can certainly take out bearings and stic...
