Main crankshaft bearing - first oversize +0.25

I'm looking for set of main bearings size +0.25 mm. Which part seller has big stock in U.S.? I've already checked RM European and Pelican Parts. Unfortunatelly not available. Original bearings at BMW are available but prices are sick.

Re: oversized pistons for M90 engine

You're right I should let the engine biulder to decide and I did so. I'm also checking from my side the pistons' producers. But final decission will be done by specialists, not me. JE refused to offer saying they have only forged with 2618 alloy. As far I know Wiseco joined with JE. CP Carrillo can ...

Re: oversized pistons for M90 engine

OK, engine was fantastic for first 5000 km (~3000 miles). The honeymoon has been finished after about 15 miles on highway at speed of 150 km/h. Engine… seized. Started from 1st cylinder (see the photo), than went to 2nd (looks a little better than 1st), 3rd better than 2nd, 4th looks good. Cooling s...

Re: How to repair torn rubber protection caps?

OK, done. Pulling out the pins from plug is not difficult. End of inflexible wire (for instance safety pin with cut tip) has to be pushed into the slot (red arrow on photo) till you fill delicate click. Than pull out the pin from opposite side of plug. The pins has small springing tap (white arrow o...

Re: How to repair torn rubber protection caps?

Thank guys for advices. I’ll try to remove the pins from plug as a first – I’ve just bough very similar new plug and see that maybe I do it somehow. Gardner Bender Liquid Tape is unreachable in my location. I can use black Sikaflex (polyurethane sealant) instead- not nice in work but better than not...

Re: M90 engine overhaul

There are good opinions for forged pistons. Anyway I used my old pistons - the rest is here http://bigcoupe.com/phpBB2/viewtopic.php?f=7&t=30466 IIRC the conrod small end oil hole faces forward and the bearing shell tab reliefs appose each other. Thanks a lot. By the way it's interesting why thi...

Re: oversized pistons for M90 engine

Engine parts are back from machine shop few weeks ago and now wait to be put together. Block is done, all camshaft journals are grinded and nitrided, camshaft-rods-wlywheel-clutch assembly is balanced, cylinder head - valve guides are changed, valve seats are machined. I cross my fingers for guys in...

Re: M90 engine overhaul

What is the mounting direction of connecting rod? Both sides of rod look the same. Only difference is a small hole on the top just below the bushing available on one side only (pointed with red arrow on the photo).

Re: M90 engine overhaul

My engine is in pieces now. Cylinder head - I have to change the valve’s guides and sealings. Crankshaft – rod journals are scratched – have to be grinded. The block - cylinders 1…5 are worn of 0,03-0,04 mm (0,0012-0,0015”) measured across the crankshaft below the "fret" at the top (I mean...

Re: oversized pistons for M90 engine

I’ve contacted Mahle – they stopped the production, nothing on stock. Kolbenschmidt even hasn’t answered the enquiry. Therefore the car part’s sellers like Pelican, Maximillian Importing Company in U.S. or Walloth and Nesch and others in Europe can’t help as well. Only way is to order custom pistons...

Re: oversized pistons for M90 engine

Thank You a lot. Your advise can be really priceless. However it will take a lot of time to manage like this. So as a first I try to find ready pistons on stock somewhere here in Europe or US. I'm under time pressure a little bit. If I find something - great. If not - I'll contact both companies.

I’ve bought the set of Elring gaskets and other parts for engine head repair. There are also metal rings to connect the fuel rubber hoses available in the set. How to use them – just press it in with hose or there’s special tool to squeeze it around the injection valve connector together with hose? ...
