I had a bad boost spike a while ago and now under acceleration it smokes like a bastard. I have oil sitting in all 4 cylinders, you take the spark plug off and you can see oil in there. The weird thing is it idles perfect not a miss.
I have already changed the head gasket and it still smokes. The stock sleeves looked fine no cracks or damage to the cylinder walls. The cooling system holds good pressure. No mixing of oil or coolant has happened. The compression test came back with the same as when I first rebuilt it.
I have forged pistons and rods, with new rings, and I did a good hone on all the cylinders. ARP head studs, head was brand new. I started it with the exhaust mani off and it smoked, so it is not coming from the turbo.
I was thinking it has to do head. Any thoughts let me know or if you need more info.
how do u know oil is in the cylinders? have u taken the head apart? What color is the smoke? if there is oil on the spark plugs, remove the valve cover and replace the 4 seals that seals the valve cover around the spark plugs. Also do a leak down test, it is alot more accurate than compression test.
i had a t04 turbo in my last ride a dc, but heres what happened my cylinders had oil in it and as well as my ic pipes, the reason for this is becuzz my oil seal in the turbo blew and, most turbo’s have warranties you just have to pay for shipping so they fix it and i just poped the head and jus cleaned off the oil and ic tubes and i was purring like a charm agian… remember to make sure to replace your head gasket and spray copper spray on before you reinstall shit together hope fully its the turbo seal in the snail…good luck
