*New day, post cont'd I have low Compression on Cyl 4 and CEL....
OK I flushed the engine, changed the oil with Castrol Syntec 5W/30 along with a quart of compression booster additive to thicken the oil and let the truck run for a bit and I noticed than my CEL came on here are the codes it threw:
P1316
P1204 Pd
P0204 Pd
P1193 Pd
Also, everytime I run the car the problem seems to get worse and worse. I noticed it was puffing out some bright white smoke after I changed the oil and filter. It almost seems like the head gasket has failed, but I don't know, I haven't had any coolant loss issues or signs of leaks, the truck never overheats. There was a white looking filmy residue on the inside of my oil cap and the used oil had a scent of gasoline in it. Would a bad head gasket cause compression loss and cause the truck to run terrible? I am starting to think my problem is either a bad head gasket(s) or the heads need to be redone, maybe a stuck valve is causing all this... I doubt that the bottom end is the problem, it doesn't burn any oil or anything. It runs beautiful on a cold start and then after 2 mins its all downhill. What should I look for guys?
