Had a blown turbo that was burning oil. Replaced it and then on startup oil filter popped loose and drained all the oil while I was trying to rev the car to keep it at running (would turn off if I didn’t rev it a little on start up).
Assume the loss of oil and pressure blew f***ed my freshly built turbo but was having trouble starting the engine as well.
So I just did compression tests. Number are 130-140-140-150 on a dry test with a cold engine. These numbers don’t seem great but don’t seem bad enough to explain the engine not starting. However when pulling plugs for the test I noticed they are all black and I just put fresh ones in a month ago and only moved the car to the road then back to the drive way. Must be from the old turbo?
Had trouble starting before and I replaced the plugs and it started right up, so I’m going to try to clean these and see if it will start. But the last factor my brain in considering is the build sheet for this car said it had 1200cc injectors, this seems crazy big? Maybe that’s part of the reason I’m destroying spark plugs so quick and even with fresh ones I have to get it reving a little before it will stay at idle. Any information is greatly appreciated.
Also forgot to mention I spun the new but most likely destroyed turbo by hand to make sure this wasn’t causing the no start. It spins though, so I'm assuming its not related to my starting issues but maybe I should try cracking the intercooler to intake tube to insure it’s able to breath with the turbo?
It still spun but seemed to spin slower then when it was freshly built prior to lose of oil after install.
