ran AE did cylinder contribution test. injector 3 and 4 came up. on PERD injector #3 was 1.6 and injector #4 was like at 7. Pulled valve covers and cylinder 3 and 5 have reman Alliant injectors in there. I pulled all the glow plugs out which were new Berus. I think oil may have got into the glow plug hole will this cause a problem with my compression test????
how much oil? if theres just a little, it shouldt affect it. but if there is a considerable amount to where its puddled, then it may a little bc you cannot compress a liquid so it will increase compression a little but i dunno if its enough to notice.
the glow plug is screws into a recessed hole. so the oil falls in when the gp is removed but like you said i don't think it's enough to cause problems. someone told me to crank the engine over and compression will blow it out thru the GP hole anyway.
