Long story short.. I did a pull from a light, was in 3rd and heard a loud bang and instantly the engine died. My wife was behind me in another car and said when this happened a large flame shot out of my tailpipe.
After towing it home checked timing and everything lined up but noticed the crank sprocket bolt was about a turn loose. (didn't pull cover to see if oil pulley lined up) Did a compression test and and got about 85-90psi on all 4. Checked gauge with air compressor and gauge works fine. Can't find anywhere that rents a leak down test kit and don't really wanna pay $40-$60 to buy one and only use it once.
I just did a complete new timing belt and pulleys along with a head gasket about 8 months ago. (arp bolts torqued down to spec) When turning the engine by hand everything moves accordingly and feels smooth. Also verified cylinder one is at tdc with timing marks lined up using a long screwdriver. Pulled valve cover and visually everything looks fine.
If it wasn't for the half compression I would think fuel or ignition is the problem but I can't explain why I would have exactly half compression on all 4 and this just happen all at once. I know I could be directed right to the problem with a leak down test but was wondering if anyone had any thoughts on what it could be. The car isn't a daily driver so I'm not in a terrible hurry to fix it or spend a ton of money figuring out whats wrong with it.
