Hey Guys sorry its been so long but had to rebuild a C15 and put it back into my cab over Kenworth so I could keep working. Thanks JoJo and FJH but i had some time this weekend to go back to the 470 and as I was turning it over there was pitting from electrolysis showing so JOJO you were correct. They all need pulling and replacing but I think im going to get rid of the old girl and let someone else deal with the it. Thanks everyone once again.

UPDATE GUYS: Still pushing so back to square one. I have another truck so I can continue to work. Once it’s sorted I will post again.

Heads are all good and being rebuilt.

I’m waiting for the heads to come back as sent them away again for magnafluxing.

Thanks MMP

Thanks Paul, mine has another tap just out of the block which I turned off.

CX. 712059.

0024” the lowest on a head and 0028” the highest on the other head though 002” between liners. But yes there is a injector with a heavy carbon build up I haven’t seen before though came out with minimum fuss, but this wouldn’t create a pressure build up through the water galleries though.

Liner protrusion is all good with .002 across all and heads are fine ….except for pulled inlet valves. So next anyone.

No cracks in the heads via dye test…..though 2 X inlet valves are pulled…where do measure liners with a slide guage ? Up on the very top of where the fire rings sit?

Thanks FJH

Thanks Vmac3 …….and I’ve now removed the heads and they look ok so now I will magnaflux before going any further…I have inadvertently chipped a couple of the liners removing the heads but the fire rings cover it so what do you guys think?

Joey, yes, same result with comp bypassed….so will pull heads or tomorrow and let you know. Thanks mate

Ok Joey tried your trick and yes I brought it up to 180F and only then it was producing large bubbles every few seconds but I didn’t bypass the compressor because I didn’t have a hose so will try again tomorrow with comp bypassed. The comp head is a reconditioned I put on the other week so I think I’m shit out of luck. what odds have with you guys being 1. Head gasket. 2. Dropped liner ?

Thanks guys and Joey yes your right of course no belt no movement so will try this today. FJH and Mackpro this is a Etech on a CX Vision so only has a single thermostat no EGR and pancake oil cooler.
