so heres the lo down. i have a built GSR block with dartons sleeves, endyn pistons, and ealge rods. and an endyn built head. complete rebuild has maybe 3k miles on it. so i had to change out my retainers so i took the head off and changed the gasket. everything was running good for three days, took it on a road trip to oregon ran great with no probs for about 400 miles. then i was cruzing on the freeway with my friend going up a small incline hill and did a 3rd-4th gear pull and at about 8500 rpm in 4th the Tach stoped climbing then instantly tones of blue smoke from the exhaust. i mean i could not even see the cars behind me!!!! so i check my wideband, running fine, engine still has power. but the second you give it gas tones of smoke, so i coast it to the offramp and park it. then i check everything, coolent, oil, and everything looks where it should be . no apparent engine noise or obvious problems, pull the Valve cover and everything is where it should be... the onlythings are i have an endyn breather kit and it was puffing alot of smoke, and then the massive amout of blue smoke from the exhaust.... ( smelled like a 2 stroke for sure!) . so i left the car in oregon at a shop and am gona go get it tomorrow. so what do youthink it could be???

 

Compression test the cylinders (rings or head gasket) and check the valve seals.

 

thats my first plan, i know the valve seals are good, had the head done less than 400 miles ago. brand new everyting. as for rings do you think just the oil controll rings? or the compression rings could have gone also?

 

well, got the car home and did a compression check, cylender number 1 and 2 had 295, cylender 3 had 120 and number 4 had 295. so tomorrow the head comes off and i guess i see what was up, heres the thing tho. the block has less than 3000 miles, and its a cometic gasket and i use ARP's so how would the headgasket blow and what are the odds new rings would just die???

 

Well, you were beating on it when it broke, so it's possibly something that was installed wrong. It's possible that something didn't get torqued properly when everything was put together.

 

had almost the same problem.. i was parking up hill with motor runnning for 3-5mins and when i took off boom blue smoke.. sea foamed my motor and 2 days later bamm no more blue smoke.. it was wierd cus i just rebuilded my head too and it scared me. i almost took off head again but i tried seafoaming it and it worked for me.. but all my compression was fine during compression test..

 

just because its redone doesnt mean its redone correctly..

 

and if your replaceing the rings i believe they come as a set so change all 4 sets on the pistons and have the cylinders honed
