My first rebuild or The results of my oil pressure concerns

[Mr Comet]

The oil pan is almost brand new so it is very straight. Does the bolt which holds on the cam sprocket need a lock washer? Can it be galvanized? Didn't get one back from the machine shop and just want to be sure. What do you use on the bolts for the water pump and thermastat Cover?

you can use a lock washer on the cam bolt, but i wouldnt, too much chance of the lock washer coming apart and little pieces of metal floating around in your new engine. i would use locktite blue on the cam bolt instead. and yes the cam washer can be galvanized. as for the tstat housing and water pump bolts, use a little thread sealer.

 

[bubba22349]

there should be a big thick flat washer under the cam bolt X2 you usally would never use a lock washer inside an engine. X2 on the Locktite

 

[Mr Comet]

No lock, blue lock tite, would autozone have the thread sealer?

"'''would autozone have the thread sealer?""
yes, we have all kinds, row 5 in Northampton, MA
(hahahahaa)
serious, no joke (that's where, here anyway...

When I was installing the oil pump and screen this AM I noticed it had lock washers on every bolt. I looked at the old one and it too had lock washers too. So I removed all lock washers and used blue lock tite on all bolts. I guess there are different areas of thought on this too. Used lock tite on the cam sprocket bolt prior to installing the timing cover and oil pan. Put on motor mounts and I am all ready for the install on saturday.

8) this is going to sound like a silly question, but you did prime the oil pump right? or are you going to use a drill when the engine is in place?

 

[Mr Comet]

No I don't mind the question abit keeps me on the straight and narrow. My plan was a drill when the engine is in place but while we are on that subject how long will it take to prime the pump?

should only take about a minute of running the drill.

 

[woodbutcher]

A little hint.When spinning the oil pump with the drill.Have someone to turn the crank a 1/4 turn.Wait about 20 seconds then another 1/4 turn,until you have had the crank make two complete revolutions.That should get everything well slobbered with fresh oil.
Good luck.Have fun.Be safe.

Well the engine went in this afternoon looks great but what's more important is how it runs which is still in the future.

 

[Mr Comet]

My lastest challenge...the old holley 6R2106 carb I was thinking of using has 2 11/16 mounting center and the head intake on the engine is 3 5/16. What are my options? Can I buy an adapter spacer to go from one to the other or will the smaller CFM carb cause me too much added heat in the cylinders? I have to invent completely new linkage for the carter rbs carb I have which also needs to be completely rebuilt. I was thinking at least with the old carb I could make sure everything else is working properly before I deal with possible carb issues on top of everything else. I look forward to all ideas. Happy father's day to all.

 

[bubba22349]

There may be an adapter check C.I. to see what they have as they make a number of different adapters. In some cases you can also slot the carb's base enough to make it fit. There are also offset studs made if you can locate them, it all depends on what Auto, Farm, or Truck parts houses you have in your area, so they might be hard to find except at a bigger fastener supply co. Good luck Happy Fathers Day!

Well first of all when the machine shop was cleaning up the block they noticed the drivers side bottom tail piece on the block had been welded back on but the machine shop said the weld was strong enough so we proceeded ahead. Well today while trying to draw the bellhousing and tranny into the block that corner piece broke off. This seemed strange to me since for a number of days this same piece held the engine up on a engine stand. Well I am open to suggestions obviously the weld didn't hold so I am wondering if any future welds would hold.

 

[rbohm]

8) a future weld would indeed hold, if done properly. that means tearing your engine back apart, furnace welding the piece back on, then re machining the block surfaces and checking the block for twisting. you dont have to machine the cylinder bores again unless they are somehow affected by the furnace welding. the next best thing you can do is JB weld the piece back on. make sure the area is super clean, and let the JB weld set up overnight.

 

[JackFish]

I'd get another block.

 

[Mr Comet]

You might be right Jack Fish but I've got alot into this block so far so i'll see how plan C works. Got the tranny in today used a piece of angle iron on the broken tail piece everything lined up good. Looking at my options incase I have too much trouble with the patch working. Can I fit a 250 cid 6 in my comet or would it be too tall? I've got another 200 block but it's all the way down in Mississippi. Thought Id use a bolt in the pin spot just for added strength. My welder doesn't think it could have been solved by welding because it's hard to get the block hot enough so I have the feeling the first time it broke it wasn't repaired correctly.

 

[chad]

Mississippi to Michigan is less of a deal than some think.
If going that route for the comet motor lemmie know. I'll back door U contacts for very reasonable shippers...

I don't see much difference in a comet engine bay and a falcon's (I may B way off here) but the Schjeldahl Brother's Performance Handbook has a chapter or 2 of guides on the 250 inta the falcon (hood clearance, oil pan/linkage, etc).

 

[Mr Comet]

Here's where I am at..Everything is installed but the carb. Waiting for small alum plug for choke surplus. Like Rich said it's the small parts..Then I'll rebuild the carb put it on prime the oil pump. slide in dist. and hookup all the wires and see if all the work paid off. Any members who have connections with the man up stairs please put a good word in for me.....

 

[wsa111]

Mr. Comet, so far so good. I would use red Loctite on the camshaft bolt.
Just take your time on the carburetor overhaul.
Its my opinion the best help is from the members of this forum.
