Stewart Posted April 30, 2017 Share Posted April 30, 2017 It's been a while (years) since I posted on here. I've just bought a 300 tdi disco. The expansion bottle is pressurising and bubbling straight after starting and the heater is blowing cold when it should be hot. With my limited skills I've come to the conclusion my head is knackered. I've looked on the forum to see if there is any preferred supplier of heads with no luck. So the question is, where is the best place to get a new head? I'm guessing Britpart isn't the way to go. Also can a normal torque wrench be used on the (new) headbolts? Thanks Stewart Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted April 30, 2017 Share Posted April 30, 2017 Could just be the head gasket? Take the head off and get it crack tested, then decide one whether to replace it, you can't test this with the head on. Quote Link to comment Share on other sites More sharing options...

The chap I bought it of has put a head gasket on it already.It sounds like he used one of those multi layer ones. Unfortuntaly he decided against getting the head checked out. Luckily the motor was cheap and it can just about stand the cost of a new head. Edited April 30, 2017 by Stewart Quote Link to comment Share on other sites More sharing options...

davie Posted May 1, 2017 Share Posted May 1, 2017 from what i know 300's just wont tolerate boiling so doing a gasket is wasted time. Turners seem to be popular place for a new head. or find a known good 2nd hand engine for sale Quote Link to comment Share on other sites More sharing options...
hangover Posted May 1, 2017 Share Posted May 1, 2017 Get the head hardness/ crack tested and if it passes then skimmed and valve heights set. Quote Link to comment Share on other sites More sharing options...
Stewart Posted May 3, 2017 Author Share Posted May 3, 2017 (edited) I've booked the disco in to be fixed (home repair isn't an option due to kids, woman and time). Looking on the Turners website they say there heads are AMC. Edited May 3, 2017 by Stewart Quote Link to comment Share on other sites More sharing options...
