@Garth, I gave up trying to find the plastic ones in good condition. I ended up with copper ones that a refrigeration buddy of mine made. He swaged it to a different size on one end to make it fit right.

This is the only chart I’ve found in 4 days that helps. I didn’t even know the name of what I broke before. Thank you.

I’m sorry, I’m a bit lazy reviewing the comments and sort out the “buy viagra", “buy addidas", “Trump is the best president ever” comments…
I promise, I’ll check the comments more often.

Due to a cam change I am short on Vacuum at idle.Is there a way to add a vac pump in the system to solve this problem. I turned the idle up and it runs great. But I have rpm on cold start faster than I like.Any advice would be much appreciated! Thanks for looking.

Replaced passenger side remote latch spring. Everything went fine until I reinstalled the outer door handle. The door handle went all the way in like it should but it will not rotate. It acts like the door is locked? The interior door handle and latch works just fine. window rolls up and down just fine, But the exterior door handle will not move? Where did I go wrong?

@Aaron:
You have a TBI? The hose should go from the valve cover to the TBI (to the spacer between TBI body and aircleaner). If it’s messed up with oil at this location, you should check if your PCV is clogged.

@John:
The green line is the vent line that goes to the tank. You have three lines attached to the tank: fuel line, fuel return line and ventilation. The vent line is missing on cars with ventilated gas tank caps.

I have a flatty here the tag says it was built 7 20 48 code c59a then in another spot it has c49a and co1ts and on the heads it is stamped 81t I am confused as to what size bore it should be is it a 239? the piston I removed from it measures 3.235 there is no marking on the piston that says it is oversize is this a standard size piston? I want to rebuild it and put it in a Canadian military pattern vehicle (CMP)
