Hi as ive explained before im fairly new to diesels. my 95 12 valve is running alright. had a thread about my fuel plate couple weeks back. anyway take the plate out runs great little white smoke but injectors are old and seals are leaking im positive of this. but if i put the fuel plate in and drive for a while i have found my afc fills with oil. without the plate no oil with the plate. a ton of oil but its not going down on the dipstick at all and just smells extremely burnt. what is going on?

 

umm ... ok so your afc is filling up with oil ... that is a slight problem ... buy I do beleive there is supposed to be some oil if I'm not mistaken ....... humm ... not sure where to point ya in this one ... not real familiar with tearing the afc apart and such .... I'm thinking that maybe the drain is plugged or something ... might want to look inside and see if there are any obstructions that are obvious and or get a book and tear it apart one step at a time unil u find the issue thats causing the problem ... thats what i do ....

 

Let me rephrase im sorry its not filling up with oil. when the fuel plate was out when i got the truck i took the afc off to put the fuel plate in upon doing so the bolts were clean and everything appeared to be in good order. then i lost all power and took it apart again to re adjust the fuel plate. this time upon taking it apart i found the bolts were coated with a thick layer of burnt (really burnt oil) so i drove a bit longer with the plate in and it still continued to do it. i took the plate back out because i wasnt happy with the performance i was getting and now i took it apart to just check on it and im back to no burnt oil or anything seeming to be wrong. i guess what im getting at is with the truck 100% stock setup (fuel plate wise) it gets a lot of burnt oil in the afc. with the plate forward a little less oil and with no plate no oil and no problem. it all seems backwards to me.

 

huh.... that is odd .... let me chat with some of my people ... check back tommrow night ... will have something for ya .... or not ... depending on what they tell me .....

 

You may be getting some bad blow by from your engine through the turbo. The boost from the turbo actuates the afc. I would check your compression. Not to scare you but those injectors might be hurting you engine

 

Yeah .... good point .... could have bad turbo seals ........ causing boosted pressure into oil system as well ...... mabe a bad diaphram in pump ?????? Might wanna go look some onle who knows these pumps in and out to get a better idea
