Hey everybody, Just got to drive my truck tonight after finishing motor swap. Already having some issues with engine. Let me give a little history of the vehicle first.
I bought the truck with a blown engine (overheated). Motor was a total lost cause. Got a crate engine, had the intake planed, but I forgot to ask them to magna flux it. Also had exhaust manifolds resurfaced. When priming the engine, I couldnt get a good flow of oil on the passenger side valvetrain. Drivers was gushing real well. Replaced everything that needs to be done on a new motor (sensors, ignition, belts, hoses, ect). After driving it tonight, at first the cloud of white smoke trailing me was incredible to say the least. After thinking about it, I remember putting a good half to 3/4 bottle of seafoam in fuel tank, with probaly less that 1/4 full of gas. Also had to top off radiator fluid a few times. The smoking got quite a bit better, but still bad. Oil pressure at start up is 60lbs. When warmed up well, it dips down to 25lbs. It does shoot up to about 40lbs when reving up. I have 5-30wt oil in it.
Now at idle when warmed up there is a pronounced tick coming from what sounds like the passenger side. The tick is getting progressivly louder when heard in the cab. I swear it sounds like a lifter, but mabey an exhaust leak? But just off idle the noise seems to go away. The coolant temp is right around 180-200 deg. I havent been able to check coolant level this last test drive yet as it is still too hot. Pressure checked rad, and system held 10lbs for my5 min test. All plugs look good too. Burning just right. My guesses to these issues are,
Possibly large amts of water in exhaust still from the blowen engine? It has been almost a year though since it last ran.
Lifter needing to be adjusted after running?
Any thoughts?
Sorry for the crappy posting. Im just a little concerned and tired now. I wont be able to respond till after about midnight. Night shift sucks, I need a nap!
BTW. 1990 K1500 5.7
