Ok, I'm at my wit's end. I just did a semi-rebuild on my TII motor (replaced rings & bearings, but no machining). Prior to the rebuild, the motor was blowing up the dipstick and shooting oil everywhere despite trying 3 different PCV setups. Passed compression and leakdown tests.
So I decided to pull apart the motor. Cylinders have cross hatch despite having 18k miles on the motor. Replaced the stock TII Garrett with a T3/T4. Realized that I only have a 2.25" SV, but I was in a rush to try to get this motor back together for a race this weekend (not gonna happen now).
The problems now
#1: Overheating. Could be the new t-stat, or a radiator cap. Haven't checked it yet.
#2: Oil feed line to the turbo is leaking above the turbo, despite being a tight as I can get it with an open wrench. I would pull the WG to grant easier access, but I can't remove the WG without pulling the head due to a custom WG mounting bracket that quasi-interferes with the oil and coolant feed lines (see pic 1).:bang head
#3: Turbo only pushes 9 PSI. I know that the 2.25" SV is a restriction, but I don't think it would cause this. The rest of the exhaust is 3" mandrel bent through a high flow cat exiting in front of the rear wheel (3 bends total). One thought is that the cam is out of time, but I don't think it is (see pics 2 & 3). My only other thought is the fact that there is NO tension on the WG when it's installed. This could be a major issue to fix since I can't remove it without pulling the head (see pic 1) :bang head:bang head
#4: Some sort of internal noise. Could be head, could be short block. Haven't checked yet. :bang head:bang head:bang head
#5: Still blows up the F*ING DIPSTICK ON SHOOTS OIL EVERYWHERE:bang head:bang head:bang head:bang head
Sorry, this is mostly to vent, but does anyone have any ideas about these problems?
