What happened to my SR20VE? So Weird !!
I just came out of a very difficult racing weekend!
Three weeks ago, we took the engine out of the car since we've had to remove the transmission, so we could take care of that front plate oil leak ( was under the head gasket where it meets the chain cover ), and to install the N1 cams. Everything went great, the engine was pulling strong till Saturday Morning when we went on the race track to finalize our set up. We are using an MSD controller so we wanted to try the different chips to set the best RPM for the VVL to kick in.
We started having an issue once the VVL Kicked in. You could hear the sound change but no power. The solenoids are ok, they get the signal, but no power. We also realized that the oil pressure was low. We use Total Synthetic 5W40. The Mechanic that used to work on the car before we bought it, advised us to use some thicker oil such as 20W50.
We did but didn't solve the problem. After two qualification laps, the engine overheated super fast so I went back to the pits. When it cooled down, we started the engine and it was knocking. Went Back to the shop, pulled the oil pan to see particles from the crankshaft bearings. All that looked like a bad oil pump. So we spent the whole night replacing the oil pump and the crank bearings.
Fired up the engine, wonderful oil pressure ( 80PSI cold ) was still low at idle but it have always been this way, took the car back to the track right before the second race on Sunday. Took the start with the same issues and exactly after two laps, the exact same things happened. Overheat, Knocking lower end.
I can't find the link between:
the lack of power when the VVL Kicks in and the overheating, and specially the lower end suffering from it.
Sorry for the long story but here I think the details matter. So frustrated.
Need you guys thanks !!
