Evo 2 blown head gasket

Nothing really out of the ordinary, it came in sounding like Ivor the Engine (apologies to our overseas and younger readers: Steam powered locomotive)

And as you can see the result of running too much boost on an old engine with stock head gasket is:


















On removing the front bumper I was confronted with this:




















As you can see it is the Bertone symbol sprayed onto the front crossmember, apparently all Evos made after Lancia officially closed the Chivasso plant were sprayed by Bertone. Maggiora assembled the car bare, then they were loaded onto a truck and sent to Bertone to be sprayed, then returned and the car was then put on the Production line. Side skirts, spoilers, bumpers, bonnet grilles were sprayed separately off the car, fitted, then quality controlled/checked and road tested on some local roads and on the Chivasso test track.


Anyhow, back to the job: The head was stripped and cleaned for inspection, skimmed, new guides fitted, valves and seats re-cut, reassembled and shimmed up ready to go back. Once it was back on the block a new water pump, belts and all bearings were fitted.
Is this any better than what your local garage would do? I have a great relationship with the local garages around here, but after seeing them take a complete head from a car with a blown head gasket which was full of emulsified oil and put it back on again as it was, well you just wouldn't do that with a 15yr old 16v Lancia head - the guides will be worn out and the valve seats pitted for sure, it's also prudent to check for wear on the cams and cracks in the combustion chamber too, a common failure of these heads.























While we were waiting for the head being skimmed we also cured the rust problem on the bootlid - the usual area on the bottom corner and fitted one of our rear bumpers, resprayed and head re-fitted it is all ready for pick up.

























The recess where the glass sits is filled with Waxoyl before the rear screen is re-fitted:
















You pays your money, you take your chances.....











Thankyou to Paul Baker for the Bertone info.

Beware the armchair expert

Ah yes, every forum has at least one, if it is a large forum then there could be many.

They will quote something they read on another forum or something someone told them as if they they just did the job themselves. Before taking any notice of such people ask them to prove their theories, it will soon go quiet.

Hmmm, nothing really floating my boat recently music-wise so lets go back in time with a classic just for the Keyboard Warrior:

Welcome to the Deltaparts Blog, here you will find, well, anything which is on my mind I guess, but mainly things to do with the Lancia Delta integrale and in particular anything to do with my business, Deltaparts. It will be a bit irregular as it's not every day (or even week) that something worth mentioning happens. I would like to try and make it interesting - at least to some people anyhow, but also hopefully accessible and readable for the average 'man on the street' so I won't bore you with loads of large words, bombastic overblown sentences or technical jargon. I will describe on here how lots of the parts that we sell came about as there isn't room on the website ( www.deltaparts.co.uk ) to explain. I hope you enjoy reading it as I do writing it, when something becomes a chore you know it's time to stop doing it....
