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? |

If I do one side, do I need to do the other as well? @slapshot i had a guy in Oregon that is a porsche and VW motor builder for many years do the heads, they can inspect them and make sure they are worth it but i would lean toward just getting new ones, due the heat fatigue to the metal , warping, cracking etc. i can PM you James's info, Ims sure also in Oregon Ben from Martin Mid-engine that used to work with Cary can both get you new heads and build them too. Regarding the source of heads, the castings are new and come from AA i believe but you want bare castings with no hardware, so they then can be built up with quality parts. Places like Stoddards, Sierra Madre etc can get those heads to but they sell them already built but not with the best parts. Phil - PS oh, i think its going to cost about $2500-$3500 for that depeding on the builder and how the heads ar spec'd. bare heads probably under $1,000 Phil |
