soo, first off, FIRST POST, woooo ! 87 widebody mt conquest. second off, my car is in dire need. i bought it for 1500 about 2 months ago, with 108,000 on the clock. hard crossover pipe, and some crappy (but not leaking) BOV changed sparkplug wires, plugs, cap, rotor, blaster two coil. oil change, k&n filter (had no filter prior) turbo pcv valve rebuilt throttle body, new injector clips, vacuum advance, fuel filter. dropped fuel tank and installed new stock pump. tank had rust hole on top, patched with chunk of metal and rtv. put power steering fluid in system. ( i ******** up.) built 3 inch mandrel bent exhaust with ebay muffler. 3 inch ebay downpipe., no cat. so it developed a tick at low rpms, thought it was loose timing chain, bought timing chain kit, bse kit and head gasket and bolts.but i ******** up and didn't get an oil pump gasket, so i used rtv, and let it cure for two days. assembled together, started first try, but now it knocks really hard. sounds like top end, but not sure. also, i suspect bad compression dude to poopy-tail piston rings. i'm like 90% on that. but i ran out of funds, and i'm an idiot with a 24 year old DD. any help would be amazing. i pulled off the rocker set and checked the lash self adjusters, three were seized solid, and one is like blown out. it is noticeably floppy, and not smooth or anything. whats the deal with these? fix, replace? i have a very limited budget, and little time. and thanks everyone in advance! pics soon.
