So this is a shorter post but I wanted to completely catch up to date and also document exactly what is going on with the car and my plans for it.
After going back down to school the car was running flawlessly, I drove it everywhere and gave everyone rides and the car didnt skip a beat. Then Drift STL announced that they were holding Drift Day 13 on the Gateway road course and I knew I couldn't miss it so I bought a trailer and made the drive up the shake the car down.
The car ran great for the the whole day apart from it getting to 220-230F after each run. This was my first time drifting this car with some real power and it felt absolutely amazing. The track was super wide and long and was 3rd gear the whole track with a 75mph ish entry and it had plenty of torque in 3rd to light up the tires even when the track tightened up a little bit.
On the last run of the day the car actually shut off as I was exiting the track on throttle in 3rd gear and I coast most of the way before trying to start it again. The car cranked super slowly like it had no battery power and wouldn't start at all even when jumping it so I threw the car on the trailer and went home still satisfied with the cars performance. My theory at this point was that the car had killed the alternator and had been running off the battery before completely draining that and thus wasn't starting. When we had jumped it it cranked a little faster and still sounded like it had compression so I figured the motor itself was most likely OK.
When I got home I let the car sit overnight before attempting to start it at the next day. With a fresh new battery the car still cranked pretty slow but I was able to start it giving it gas and it had a ton of blow by and also sounded like it was running on 2 cylinders. after revving it for about 10 seconds it cleared up and magically had no more blow by and ran great. I took it around the block and it felt like it had all of its power and was running strong and charging at 14V.
A couple days later I decided to take a log to make sure everything was OK and I did a pull and as I hit 4th WOT it died in gear just like it did at the track. I was able to bump start it in 3rd and get home but after looking at the log it all looked perfectly normal. I took it out a couple more times and when driving normally it was perfect but anytime I did a pull it would shut off, then would crank super slow or even lock up the wheels if I tried to bump start it, then would do the same blowby misfire thing for 10 seconds before being completely normal.
At this point I think its got to be fuel related, Im thinking either a stuck injector or a sticky FPR that's hydrolocking the motor and washing the cylinder walls, Ive also done quite a few oil changes after the event and the oil reeks of E85 and also there seems to be quite a few shavings on the plug since the event.
Also since the event my oil pressure has been around 10psi at 800rpm idle on 20w-50 so I think there has been some major damage from this hydrolocking incidence. Ive done a compression test and its still good and even and the car still runs, idles and drives perfect until I do any sort of spirited driving or WOT pulls. Because of theses issues and the fear of it getting worse Ive decided that Im gonna pull the engine to do a new oil pump and check the bearings. Im thinking that there might be metal from washing the bearings which has scratched and scored the oil pump gear causing it to be low. It sucks but at the same time id rather be safe then sorry, while its out ill probably do a bigger turbo and verify the timing as well as switch back to stock cams and a new fpr with cleaned and tested injectors. We'll see how it goes but Im just hoping I caught this soon enough and since the engine still starts, idles and revs fine I have high hopes that Ill be able to fix whatever is going on. Shoulda went K series smh lol.
