Things to consider when mounting a 250 E engine

Hi All,

I am in the process of mounting my freshly rebuild 250 GTE engine. I have done several demanding engines in the
past but each engine has its specialities. I thought it might be helpful to collect things to consider when doing a 250 engine. Especially helpful for me at the moment

Things like:
- two of the locating dowels for the head must be hollow as they act as oil galleries
- tension of springs in rebuild kits for water pumps might be wrong/ if in doubt try to use old spring
- timing marks are just for assembly of engine, exact timing must be checked differently using exact opening of inlet/ exhaust of number 6/12 piston according to TDC
- use 0.5mm stainless sheets to hold o-rings in place when mounting chain case to be able to mount headcovers later
- check mechanical pump action and make sure that there is no play in actuating lever
- ????

I am sure you all have your things which should be considered. This sight might be a means to preserve it for others.

Any hint, idea, experience welcomed. Thanks a lot.

Dear turbo-joe,

good hint. I am still in Padua and found a original clock for 100€, Spinners and lots more. Was worth the trip. Flying back today.

Thanks
Christopher

 

Some more hints:

- don’t forget o-rings at the back of the engine at the end caps. Mount with rtv. This one is coming from Tom Yang. Always helpful and worth visiting his site

A good tip I read in Toms blog is also to check the crankshaft for free turn after mounting of each rod and piston before mounting the crankshaft end seal (simmering in my case after conversion).

Two more:
- To get the oil pan to seal properly Ferrari used a special paint and I have read about different ways to try to seal it. I had mine vacuum pressure sealed by a company in Germany. This way every tiny crevice is sealed.

- Another one I was told is to use thread seal at the base thread of the head studs.

By the way - the tip about the stainless steel sheets for mounting O-rings way above is from turbo-joe ;-) not me.

Best regards
Christopher

 

Thanks. Lots of parts and weight ;-)
But it is a delight to carry those parts...

 

I am sure others must have also good hints?

Thanks
Christopher

 

I found them on Auto Epoca in Padua, a classic car exhibition and market. This way I got them for a reasonable price. You can get new ones from Borrani or GTO Engineering. As you are in France you could get new ones from Münchner Oldtimer Reifen. They have the different types on sale for around 260€ per piece. Hope this helps.

Sorry, thought you were speaking of Borrani spinners. Do you have a picture?

 

Have you tried the usual suspects? Gto, Eurospares, Superformance, Autoricambi Epoca....?
Picture would help.

 

Speak to Vern Lyon at Gto if he has them. They have lots of used parts also. Alternatively speak to Sergio of Auto Ricambi D’Epoca.

P. Coppola might be worth a try as he has lots of used parts, but seems to be always on the high side of prices

And for sure as always all the guys in the US but the shiping and taxes are on top.

Hope this helps
