Mine broke the tensioner stud. Thing kept running long enough for me to extricate it from the embarrassing situation it was in. 5 bent pushrods and three broken rockers. Even the bronze cam followers survived.Quote:

Did a belt on a FIAT twin cam once. Only the crank was salvageable on that one. Admittedly she was doing some revs at the time.
Progress has been a bit slow due to work and waiting for uk parts delivery .

So if you ever wondered what your inlet valves look like in an egr engine this is how... crazy to think someone in their wisdom thought egr was a good system..
Pulled the valves on 1 of my heads and 3 noticably bent valves and 3 that are suspect so am in the process of refitting diffent valves and new valve seals to that head then will do the same on the other head.
Oh and you can change the oil cooler in less than 30 minutes with the heads off ... and 20 minutes of that is cleaning the valley

I’m sorry to hear, but unsurprised you have bent valves. It’s probably a great opportunity to have the heads professionally reconditioned, valves replaced, reseat, new guides and stem seals. I guess it depends how long you’ll keep it
I lapped in 12 valves today , fitted new valve stem seals and if i could work out an easier way to fit those bloody small collets i would hopefully get the other head done tomorrow, then i can start putting things back together ..Quote:

The car is up and running.. after sorting a fuel pressure issue which turned out to be leaking lines at the hpfp..
All in all i am surprised in how little damage there was for an engine that failed @90+ kmh towing 3ton van. In saying that the top rocker gear did cop a fair old bashing..
I put the 6 valves i thought were bent into a freinds work shop and it turns out only 1 was slightly bent and in his opinion would have been usable if needed.. my issue with it locking up turned out to be a roller rocker that had lost roller pins that i didnt notice and it would get to a point then it wouldnt roll causing the rocker not to push the valve properly... in saying that im glad i went to the extent of removing the heads and seeing no piston crown or valve damage..altho it added several more hours and lost skin to the job.. plus needing to get a bit inventive when refitting the passenger side head
The 2 hardest parts of the job were the vaccumm pump and the gear that drives the hpfp... there just isnt the room to do these easily with the body on... you just need to have patience and double jointed wrists and fingers.. the up side was it made fitting a new oil cooler very easy...
All in all its really an economic write off if you cant do it yourself as these cars are selling so cheaply now.. I havent added it up to the last cent but its cost me $2500 in parts all bar the heads from the UK.. Also i havent added up the exact hours i spent on it but it was 1 day a week for atleast 8 weeks plus a few extra hours here and there.
i did fit a new oil cooler and a new vaccumm pump so i could have gone cheaper if i reused the old ones but i know im not the lucky person who can get away with that and it not come back to bite me... i was lucky that i picked up a set of 2nd hand heads which had all the parts i needed which got damaged on mine so this saved me a lot of $$
I have a oil leak to fix but other than that time will tell whether i did the job any good or not..
Thanks to all for your imput and a extra thanks to Dazza for his advice , the loan of a crank seal fitting tool and the offer of parts , the forum is better off for having people like him on it..

Glad to hear it has all come together. A friend has just had his 2.7 go bang - this time it is an actual broken crank which is unusual for a 2.7 - same spot as a 3.0 as the front pulley is wobbling around.
