Bluemoon Posted January 6, 2013 Share Posted January 6, 2013 just finished putting a new 300tdi cylinder head and new gasket on today after having the whole xmas bad , passing the sickness flu around the house with the kids. Its was all torqued up according to the manual. As soon as I started filling with water I noticed coolant leaking from the rear of engine, a drip five every seconds, thought strange, thought maybe it might go after firing up but still there. The cylinder head and gasket are from Paddocks, any thoughts. Brian Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted January 6, 2013 Share Posted January 6, 2013 Can you actually see where it's leaking from? Quote Link to comment Share on other sites More sharing options...
dirtydiesel Posted January 6, 2013 Share Posted January 6, 2013 I have come across the core plug in the back of the head leaking. Quote Link to comment Share on other sites More sharing options...
Bluemoon Posted January 7, 2013 Author Share Posted January 7, 2013 Ive had a good look, and it looks like it straight out from the head gasket, definately not the core plug, I've wiped the wet bit and you can see it weeping from the gasket, at the very back , and very back right hand side.

Boydie Posted January 7, 2013 Share Posted January 7, 2013 If the head is new and you torqued it up I think your block is warped Quote Link to comment Share on other sites More sharing options...
Se7enUp Posted January 7, 2013 Share Posted January 7, 2013 Are you certain your torque wrench is working OK? I only ask as I had one fail once while building a Mini engine. It felt normal when used and the "click" was as it had always been. The only problem was it was measuring around 50lbs less than it should do. This was evident when we started up the engine and saw combustion on the outside of the block! After replacing the torque wrench, we decided to strip the entire engine as a precaution. I'm glad we did as one of the main cap bolts could be turned by hand! Quote Link to comment Share on other sites More sharing options...
moose Posted January 7, 2013 Share Posted January 7, 2013 Are you sure you didn't put the head gasket on up side down? ( i have done this once ) you can tell by the location of the gasket thickness indication holes. Also what type of gasket is it? Is it a multi layer steel (MLS) one, or composite? Did you clean the deck properly? Quote Link to comment Share on other sites More sharing options...
Bluemoon Posted January 8, 2013 Author Share Posted January 8, 2013 it was a three layer one, all separate two steel outer with a composite inner, deck was nice and clean Quote Link to comment Share on other sites More sharing options...
poohbear Posted January 10, 2013 Share Posted January 10, 2013 I haven't played with a 300, but could it be a fouled locating dowel hole or bottoming out? Dave. Quote Link to comment Share on other sites More sharing options...
