4G63T Oil Blowby
I have a built 96 Eclipse GST. It was runnin terrible when I bought it and so I took it to Mainstream Performance. Before I took it to them, it idled okay and it never leaked anything or burned any oil or anything like that. While they were dyno tuning it, they fixed all the problems but two new ones popped up literally while it was on the dyno.
The first one is now it idles terribly, the guys at Mainstream said it needs a new Idle Speed Controller....which kinda sucks cuz it's like $280 for a new one and they're not easy to get to. On top of that, it wasn't an issue before I took it to them. So, could dyno tuning my car cause the ISC to go bad?
Second one is while it was on the dyno and they were taking the engine all the way to redline, every time theyd do that, oil started shooting out of where the dipstick goes into the block. It never did that before either. So, again, could dyno tuning my car cause that oil leak?
Any advice ya'll give is greatly appreciated. Thanks!
