ok the 2000 trailblazer i sold my friend last year only has 88lbs of compression and will not start. also i pulld the pull start off the crankcase and thier is all kinds of gas around the starter. is it coming aroud the rings and into the bottum of the motor. were should i go for the rebuid kit and how much. a friend of mine is going to rebuild it for free he will just need time and the parts please help. could the oil injector have caused this and how can i check it will its tore down. thanks in advance.

 

the motor dont need to be borde out does it....is there any scratched on the cylinder walls???....there should be around a 125 pounds of compression dont quote me on that cause im not sure?????

 

weisco......... contact rittercycle.com .. they are the trailblazer pro"s

 

if the oil pump had quit it would have seized the engine.

 

the engine is not siezed but it only had 88lbs of compression. we have the motor out and are going to teardown tomorrow to see what it needs. i know for sure he is going with a weisco piston. is there any way to check the oil injector while we have it tore down.
i also broke the tranny apart because he lost reverse. the c clip had spread and moved out of adjustment we put it back in the slot and now have reverse.( tested on the bench by hand ) should you use silicone when putting the 2 halves together. my old tb looks pretty bare. no motor no tranny. crying out loud.

 

either broke the rings or maybe the piston skirt, blew a head gasket. you'll know when you get it apart.

 

it just needs a rebuild..im sure you didnt break anythingin there because 88lbs is still alot of pressure because teh stock max is around 120 so you probably dont have anything broken inside

 

this is true if it has been running poorly and didnt have the power it use too. but if it was running great and all of sudden stopped then maybe soemthing let do. i always think the worst anyways. chances are tbsleeper is right.

 

Get the cylinder bored to the next piston size and be done wit it.Get you a needle valve and seat from a dealer and fix the gas problem.Plus when you park it turn the fuel off.

 

tore down today. everything looked good even the piston. going to order the top end rebuild with weisco piston probly tomorrow. clean it all up and put back together. hope it will run. the tranny is still in 2 halves do i need to use silicone when i bolt them back together? i do not think it need the needle seat. my buddy said he cranked on it forever so i think he just kept fooding it and the gas worked its way down to around the stArter.
