Title: engine failures
Post by: Anonymous on January 17, 2005, 09:06
after reading a few posts just recently about more engine failures, its got me thinking and worrying again about the build quality of the MR2 engine.

I know people have suggest gutting the pre-cats to help the problem but just out of interest, has there been any engine failures reported after the pre-cats have been gutted??

Ive gutted mine so i'm hoping this is my saving grace from the dreaded engine failure.

Suppose i'm just looking for some reassurrances cos i would hate to have to get rid of my 2

cheers

Alan

I'm now on 40k miles (pre-cats were gutted a while back) and it has never missed a beat or used oil, so I would hope that it will caeey on as strongly for a good while yet - unless the boost kills it!

The pre cats on my 03 started to fall apart at 10K so I helped them with a screwdriver   s:? :? s:?  
I now have 25K on the clock without trouble, use no oil.
I dont think anyone has blown a known good engine after gutting the pre cats but I might be wrong.

I'm very much a novice when it come to the 2 and a little concerned over these pre cat stories so perhaps some one could enlighten me on the following?

 - What signs do you get when they start to go?
 - How do gut them and at what cost etc.?
 - When/what mileage should I start worrying?

As my car is only six months old I've got plenty of warranty left so I'm not to concerned at present but I am wondering if I need to do something to prolong the ownership or at what point I should start to think about getting shut.

Thanks,

Andy

if nobody answers the above questions use the search tool and enter pre-cats AND gutting. This should answer all your questions as those questions have been covered many times before

heres my quick answers to your questions

loss of oil is a sign

you gut the pre-cats out of your manifold. This can be done by yourself with the help of a screw driver and hammer.

there doesnt seem to be any set mileage when the problems can occur
