1970 Duster AlterKtion, 4 Link, LS/T56/Turbo and Minitub
Aaannnd for the next episode. Got the car together and started up. It was smoking quite a bit of white smoke at first. Which I figured was the leftover coolant burning off. Then the smoke turned blue... I took it up the road and it doesnt seem like it was quite as quick as it was before it blew the HG and I couldnt see the road behind me from all the blue smoke lol sigh. Back to the shop. When I got the car back in the garage oil was dripping out of the tailpipe at the BACK of the car O.o oh boy. So I pulled the downpipe back off and there was oil everywhere. I went to start the car to see if the turbo was blowing oil out of the seal aaaaannnnndddd the BRAND NEW starter **** the bed..... thats when I went inside.
I called up VS Racing and ordered a turbo rebuild kit just in case (99% sure thats the issue). I also am going to send the summit starter back and upgraded to a powermaster high torque starter. That should be here next week sometime because I'm shipping the old starter back today or tomorrow. I'm also going to do another compression test to make sure nothing else is hurt like a ring land that I cant see etc from the HG blowing (maybe it was a boost spike or something weird). Hoping maybe the O2 sensor was causing a false reading from all the oil making the car not seem to go as good.
When I blew the HG originally I had said it blew the heater hose off AND started leaking oil. I couldnt quite figure out the oil part yet. But when I called VS Racing and explained the situation he said something that I overlooked. I told him I blew the head gasket and I understand that if the gasket let pressure into the lifter galley area it could pressurize the crankcase. But no way it would blow pressure up past my oil pump! Being my first turbo build I overlooked a key component. He says "Isn't your turbo DRAIN line a 10AN line back to the oil pan?" >.< well I'll be damned. So it seems that when I blew the head gasket, that 21 or so PSI went back up the drain line and dead headed the already 75psi oil coming from the pump causing all sorts of chaos. Learned something new! Hopefully you guys did as well from todays episode of Duster Devs Nightmare.
Also ordered this to help vent the crankcase, since apparently the factory 3/8s lines from the valve covers aren't sufficient with a boosted motor.
