Do you still have the 87 DME? How much do you want for it? I don't have an extra one but I have heard of people keeping spares.
I would be worried about the 3 BAR oil pressure at 5K too. Fuel pressure sounds good. I didn't know it droped that low with the vac lines on. I thought it should stay around 44 PSI +/- maybe 5 PSI on cruze. I have a FPG mounted to my fuel rail. With my stock injectors and stock FPR I was getting 40 PSI. I put in 36# injectors and an AFPR and I bumped it down to 20 PSI. But if the book says that's normal then I'm sure it is.
I just did my cam gasket and I'm not in a big hurry to go pull it off to see what mine looks like.
I wish the PET had the other side view of the head.
How's the oil level? When my n/a used to leak oil I would notice my oil pressure get lower as I lost oil. It was still in the good section of the dip stick but a little on the low side. If I filled it to the upper limit I got my normal oil pressure back.
This is from the FAQ:
"For highly modified vehicles pulling very high cornering G’s, it ispossible that the oil will slosh away from the pickup causing theengine to starve for oil (read: big engine damage). The 89 944 Turbo and S2 have an additional pan baffle to help avoid this problem.This part will fit other 944’s. The Oil Pan Baffle part number is 944.107.389.03 and costs approximately $65.97. This may not fix the problem entirely, but it may help."

FYI: I don't know where the "big engine damage" section is. I looked for it, but I can't find it.
