How can I know if my engine is bad

What year is your sprinter?

Ruva A.A 2006

Diesel in the coolant? Strange ... I know if there is a diesel fuel in the oil that could be your high-pressure fuel pump

Ruva A.A I know so strange. I flushed it all out and ran water into it for over 15 minutes, added the appropriate coolant and it’s been a lot cleaner since. I’ve ran it over 600 miles City only and so far okay minor traces of diesel in it though now it starts to look like oil. Any idea if it’s oil in coolant? Thank you for your replies. :)

@@josemadrid7932 I have the same problem. Diesel in coolant. No cups so I think it's a crack in the head.

Same problem here. What causes it and what's the solution?

Yes I would install them the way they are, I noticed on my Sprinter, what I did in the past was squeezing them and rotating them clockwise and counterclockwise while I was squeezing on them, sometimes a little bit of black, thick , old oil would come out of them, but it's not necessarily, as long as you change oil every 9,000 k should be fine

@@RuvimAbaras ruva, the problem that occurred with my head it had 2 intake valves bent , what could of caused it. i checked the lifters and 2 of them did not squeezed. which tells me that stock the valve a bit down then when the piston went up it hit the valve and bent it. or what else can of caused it to bent.

Was your Sprinter been parked for a long time before you start cranking the engine?

@@RuvimAbaras NO!!! the only reason i can come up with is. my valve got bent was probably one of the lifters got stuck and did not squeezed,in when i first installed the head, before i installed the lifters girdle i checked the lifters and all of them squeezed in easily. i got the engine running started out good then in started to misfire, that's when i checked the cylinder pressure on each one they read 295 but #4 no pressure.which was the cylinder with the bent valves. im going to install the head with the fixed valve's. then turn the engine. hope this time it WORKS. ill let you know, i have 3 sprinters, the other 2 i overhauled 2 years ago no problem both running GREAT. thanks. im from south Texas, Laredo.

You'll have to take the head out,

In order to remove a piston it is way easy to yank the engine out get the head out and fix it on the stand,

Yes I would remove them first, as far as Cam caps I just carefully hand tighten them several times

minimum $2000 to do the headgasket parts and labor, re-using your old cylinder head. parts cost for new cyl head is 1500-2000, estimate at least $4k USD for this service

Otto Doktor The coolant was leaking from injector nest

@@RuvimAbaras I have extreme blowby on the oil cap after replacing copper injector washer. The oil is gushing out while idling. Do you think the piston rings are shot, or a crack in the cilinderhead?

Otto Doktor Sounds like excessive compression in block, I would start with cylinder compression check

Broken cylinder? Oh wow how did that happen? Yes definitely change the Engine block!

Yes it’s bad :( you need new motor block
