I was blasting through 4th gear on the highway shifted into 5th and shortly after noticed a severe decrease in power. I got off the freeway and my turbo II isn't running smooth at all. It's hard to get it rolling. I park it at my friends house and try to start it again. Won't start. I come back today and it starts up and runs the same as last night. I get it to my house and same story, when its warmed up it won't start. I pull the plug wires to see which side is messed up. The rear ignition made no difference when I pulled it. I check the compression on the rear and get 3 50psi "bumps" on a pretty cheap compression gauge. Does anybody have any clue what happened?

 

Well if that gauge is accurate and you are only getting 50psi, then your motor is finished.

 

you should be seeing 90 psi bumps or more on a standard pressure gauge...

does it idle like crap?????????

 

Sowhere, in the distance, over the apex seal graveyard.. I can swear i can hear "Taps" being played, softly, on a Racing Beat downpipe

 

I really need to check the compression again on a better gauge to be sure.

i swear to god i just peed myself laughing.

 

Thanks a lot man. I did the pull the leading plug and listen to the pssst's, I came up with 2 weak pulses and 1 strong pulse, would that mean a cracked apex seal maybe? Or totally blown

 

a cracked apex means its totally blown, as in...start saving up!!

 

when u first start ur car does it run fine or does it run shitty? cuz i have the same power loss when warm but it runs fine when i first start it and drive it and when ur car is screwed up what does it idle at? mine seems to idle at like 250 it shakes like a **** at around 500) i also have a 87 n/a im getting quite stressed out trying to find out why my car is doign this. side not where do u buy the compression testers (i dont meen to highjack the thread)

 

I know a cracked apex seal is just as worse as a blowed up one, but with the cracked one there is a less chance of a f*ed up housing, or turbo.

 

Mine just runs terrible all the time, its blown for sure.

 

pull the engine, the song is over..

 

i took my cat off and ran it with a one foot in length pipe off the header( verry verry loud) and it ran fine. hopefully it was my cat and nothign elts
