Yesterday just before getting home I heard a click from the engine then again. It wasn't steady, just every little bit I would hear it. I could feel that I lost power and it even stalled once at a stop light. Since I was only a couple block from home I just keep going.
I found that cylinder 3 could only produce 20 lbs of compression. A leak down test was 22% with most air coming out of the intake. For reference the other cylinders were 100 to 105 compression and the leak down was 18% to 20% with air noticed just in the oil filler hole. I don't know how accurate my testing tools are since they are cheap ones I got from amazon and harbor freight. I took off of my valve cover for cylinders 3 and 4 and with cylinder 3 at TDC I have over 1/2 inch of play with both valves and the pushrods are of course way loose. I haven't removed the rockers to pull the pushrods out yet to see if they are bent. I will do that after I pulling the engine either tomorrow or this weekend. How screwed am I? Thoughts on best and worse case? Here's a video of my loose rocker Video of rockers |

914sgofast2, what is P&C's? Pistons and cylinders?
DRPHIL914, Who did you send your heads to? Was it less than buying new heads? I order a scope last night. I might pull the heads off before it gets here though. The motor's coming out tomorrow. Who makes a good quality head that's reasonably priced? If I do one side, do I need to do the other as well? |
