Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

How many years do they last ? I'm engine out and doing all preventive Anyone have one fail ? Advice appreciated

POST 2Original post

I would only replace it if it was corroded or if there were too many bent fins and lost it's cooling effectiveness or else I'd just leave well alone. Based on the fact that you're in fl, you can probably rule out the first scenario. Check the fittings and hoses though and make sure they are still in good shape.

One of the reasons they fail is internal membrane Breaks down ( suggested cause is use of wrong Coolant) image-526095408.jpg

POST 4Original post

Hey awesome. Looks like were doing the same project. My oil cooler looked great so I felt I best leave it alone. There are many other things you can do while its out. Can you post some pics of your project. My engines about ready to go back in unless I decide to change the IMSB again while its out. Watch out because many do not approve of us doing this.

image-2667804321.jpg The great thing about this Indy is he invites you to come into work area and explains the entire Procedure and you get to look at a dozen race cars a dozen vintage cars I got lost looking around the shop and took more pictures of everything except my car In regards to the oil cooler, much like the AOS The fail is inside and can not be detected by exterior appearance

Does your car have the "wrong" coolant in it? What is this "membrane" you speak of? I think of oil coolers(at least traditional ones) like radiators where you have end tanks and bunch of liquid passages or channels usually made from metal with fins protruding out of them.

POST 7Original post

Im sorry, my mistake. For some reason I assumed you had done this yourself. Make sure you look at coolant hoses, vacuum lines, oil sending unit, water pump, chain tensioners, vario cam sol. seals, coil packs, plugs, pulleys, AOS/OVS, oil filler tube, clutch and all related parts/systems, IMSB, RMS, etc. Everything is so easy to get to with the engine out that its a perfect time to do it all. I see he seperated the AC lines instead of removing the comp. Was the egnine that clean or did someone clean it after drop?

POST 8 / ORIGINAL POSTEROriginal post

It was this clean

POST 9Original post

POST 10Original post

I think that there was one case, where the oilcooler was internally broken and causing intermix? I replaced mine, when I rebuild my engine. It's less than 200usd part...
