hey guys, im fairly new to the forum, and have been browsing some threads for a bit now. so here I go, I built a turbo setup for my 96 f-150 m5od 4x4 obd2 maf. the setup is a draw through maf, using the stock eec programing, and 19lb injectors from a 4.6l mustang gt. the turbo is from a late eighties Volvo 740 station wagon td04. no fancy piping as I was just using spare charge pipes that were collecting dust in my garage. the waste gate is set at 8psi and references from the compressor housing, the engine reads 6psi at the manifold, I pulled the base timing back 4 degrees, and am running copper core autolite plugs, after removing the ngk vpower plugs. truck runs awesome considering no tune added to the system head was replaced 6000km ago, performed a bowl hog, and intake runner clean up, exhaust was polished but grinding was left to a minimum. I had to steal a dual core rad from another truck to keep the engine temps cool. truck ran happily at 6psi. at the moment I do not have an air to air or "intercooler as gas guys call em" at this time, before I do any more hi way cruising I will be installing one. at 110km/hr unit is making a constant 6psi suspect very hot intake temperatures. have not noticed any knocking or irregularities, under heavy loads (long 4th and 5th gear pulls). soobeing caught up in the boost cycle/addiction :nono: I moved my waste gate signal to the intake manifold. truck was making 7 psi under full throttle and 9-10 psi under part throttle. once again no knocking noted, took the truck out of town for a highway cruise 60km or soo and back. truck started to miss on cylinder 6, and started to smoke white . suspect head gasket has failed. only smokes when hot and idle. I ordered a set of head studs. does anyone have a suggestion for head gasket and to help it live? im going to leave the truck set at 6psi for future use.
