i2tall4abike Posted April 14, 2012 Report Share Posted April 14, 2012 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) BOVchanged sparkplug wires, plugs, cap, rotor, blaster two coil. oil change, k&n filter (had no filter prior) turbo pcv valverebuilt 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.

psu_Crash Posted April 14, 2012 Report Share Posted April 14, 2012 If you had collapsed lifters that would tick like a mad man. Those hydraulic lifters need good oil pressure to pump up and stay that way. Using RTV on the oil pump is a very bad idea (as you already know) Some of that RTV could have got into your system and blocked an oil passage in the head or other places. Did you notice any foreign material in the rockers, shafts or lifters? Link to comment Share on other sites More sharing options...
Technology Posted April 14, 2012 Report Share Posted April 14, 2012 foreign material Now's not a good time to be xenophobic! Anyway, OP, you should replace the broken lifters with good ones, and to check oil flow, you can take the valve cover off and surround the head with carboard then crank or even run the car for a short time to see if oil is flowing well through each rocker.

Komeuppance Posted April 14, 2012 Report Share Posted April 14, 2012 i ******** up and didn't get an oil pump gasket, so i used rtvThere's your problem. Take off the timing cover and install the oil pump correctly with a gasket. -Robert Link to comment Share on other sites More sharing options...
i2tall4abike Posted April 15, 2012 Author Report Share Posted April 15, 2012 so i'm about to order lifters and oil pump gasket from dad. what is the easiest way to change the gasket without ripping everything apart? i just changed all the fluids and gasketed everything, so i don't want to take unnecessary and costly steps. thanks for the help, btw.
