MY GTR I WAS PICKING UP MY WIFE AND JUST standing the car sound increible wierd, the oil presure was good and water was good, it became in 5 cilinders and i shut it off, y try to crank it up, and sounds that the engine have no compression, so i thought that the timing belt broke, but no, after 5 min trying to start the car, the car start and a big oil cloud behing, and it start like 5 cilinder, i drove the car to my mechanic and the car was in 6 cilinders, no boost at all, nothing, so i thought the turbos were gone ,but no they were good.
we check it to day, and cilider 1,2 have the same leak 80% and oil on the plugs, how can be possible that 2 cilinder together like that 1,2have no compression.

what happen to my engine??
1- how it is possible the 2 cylinder die together and have the same leak!!!??
2- could the oil passage from the head gasket have rip and that's the compression leak and the oil to the cilinder??

please help, until monday i will pull out the engine!!

thanks

Yes, its quite possible for a gasket to blow between cylinders and therefore lose compression on both at the same time.

The oil feed for the head generally runs through the gasket too, So its possible for that to get in there but this doesnt happen very often, Are you sure its oil on the plugs ? or have they just got sooty and wet with fuel ?

Either way it sounds like the head needs to come off if you have no compression on 2 cylinders.

1-Are you sure its oil on the plugs ?or have they just got sooty and wet with fuel ? well they car burn increible amount of oil, i had to drive like 5mile and the car waste like quarter and half of oil,
i pull the plugs out and cilinder 1,2 was the same are wet, smells more fuel ,than have oil on it, but it must have oil comming in, this case maybe like you said comes from the oil gallery close to the cylinder.

before it happens heard like alot noise, i thought that the timing belt was gone, i can figure out what was that ugly sound.!! could be that the gasket broke and the metal ring of the stock head gasket, went to the cylinder and make something funny inside??

thank mate, hope to hear some more of this

Whatever it was it probably was an expensive sound to hear

I guess the head is also damaged in this fashion ?

Looks like something has gone in there that doesnt belong, Though I wouldnt like to guess what it was as I have seen liquids cause this kind of damage as well as solids, But if you plan to rebuild that engine I would advise you spend a lot of time working out what went in there to prevent it happening again, And also make sure its all cleared out too.

Its hard to say much else based on those pics tbh, Do you have pictures of the Gasket and the head as well ?

The choice on a new engine or rebuild is entirely up to you, You will need to check both options and see which one you like best, A brand new engine, or one thats rebuilt as good as new. I guess the cost will play a part in your choice as well.
