killshot_kustom Posted July 19, 2009 Share Posted July 19, 2009 I had the heads re-built and surfaced, re-sealed everything, new water pump, new timing belts. Used perma-torque head gaskets. Emisions and EGR stuff gone, webber installed. heres the compression i'm getting ____Driver_ 115 155 125 155 It's smoking white after it heats up, comes up through the engine bay, seems to be comming from the y pipe before the Cat so i assume I have an exhaust leak too. I'm gonna pull my cat and see if it's just residual crap burning off. Engine got warm pretty fast, I shut her off before she got past half way. I still have to adjust my webber, and thin out my coolant. Grabed the concentrated solution not realizing it and filled up the radiator. So should I be looking at anything else for the smoke? What are the factory specs for compresion and the variation? Thanks, Dan Link to comment Share on other sites More sharing options...
GeneralDisorder Posted July 19, 2009 Share Posted July 19, 2009 Typically I like to see 140 to 160 on the comp. No more than 10% difference between cylinders. You have about 26% there. You should at least run it till you get everything normalized (oil pressure, coolant temp, no smoking, etc), And retest the comp. If you still have comp. issues, and you had the valves done? Then I would say you might have a couple scored cylinders or poor ring sealing. That's assuming that the smoke stops, etc. Perhaps the head gasket didn't get torqued down quite right - you did wire wheel the bolts, chase the threads in the block and oil them before torquing yes?

idosubaru Posted July 19, 2009 Share Posted July 19, 2009 Definitely low numbers on that side. The timing belt isn't off is it? Have you run it a bit, they like to run poorly and loud for a bit after they've been opened up. Burning off coolant is normal as it runs down into the exhaust when you're disassembling the engine unless you remove the exhaust first. let us know when you're sure you're loosing it.

Fairtax4me Posted July 24, 2009 Share Posted July 24, 2009 Sounds to me like the head gaskets didn't seal right. Is the white smoke coming out of the tail pipe or just from under the hood? Link to comment Share on other sites More sharing options...
