4g63 Help!!

I'm having problems with my GST recently it bogged down and died at a stop sign. It turn back on and made it down the street to my house. She makes an attempt to start. compression test on plugs gives 125-0-30-60. Any Ideas

Holy... :eek: :uhoh:


That isn't good... Were you driving it hard before that? It could be many things... Blown head gasket, bent valves, blown rings, etc...

Something in that motor is blown.

Aww crap... What would be the best way to go about this??

There's only one way to go about it... Complete rebuild or a new motor...

There are any number of things that can cause the shitty compression including bad rings, compromised valve seats, or a leaky/pinhole in the headgasket and the no compression might be a hole in the block, demolished headgasket, bent valve, or a combination of the aforementioned.

And Blackcrow is right, you're going to need a new motor or that one rebuilt, that shit isnt easy or cheap to fix.
