jUst swapped a gsr motor in my em1. I turned it on and it was smoking so I took off my spark plugs and notice the #1 plug was wet. I also have oil in the #1 exhaust port. I did a compression test and I had 245 across the board. I did a leak down and all cylinders were at 5%. I did a wet test and all cylinders jumped fRom 245 to 265. could I need valve guides? the engine has fresh oil but in the exhaust port , it comes out Black. any info would be great.

#1 plug is wet due to o ring on the valve cover. and 145 even to 165 psi compression seem low to me.

 

oops I meant my compression was 245 and went up 265.
let met edit that.

 

bump cuz I need help.

it has new o rings and it not wet in the spark plug hole. im think im gonna change my valve seals next week

 

I looked in the exhaust port with the problem and I see that the valve stems are wet with oil and the other 3 exhaust ports are dry as can be.

 

hmmm i would check your cylinder #1 valve guide seals. it could b that not all the oil is getting burned up on compression and getting pushed out the exhaust ports on the exhaust stroke or it could possibly b the oil is leaking in through ur exhaust valves directly and getting pushed out. if the oil control ring is ok the only other place oil could come from is ur cylinder head.
best of luck

 

sounds to me like a valve seal went, had it happen on a couple of my motors and my exhaust port was oily

did the seals fix the problem

 

well i just got my head back from the machine shop. i got the hole thing rebuilt. i slapped it back in and oil is still coming out the one exhaust port .
i guess its the oil rings. now i gotta rip it apart again

 

when i took my intake off my fresh rebuilt head, there was oil in my intake. keep in mind i took it apart and cleaned it the first time when i put it back together. how is there oil getting in my intake mani. my pcv wasnt even connected.
