Head Gasket Failures - survey

[Pip1968]

Hopefully there will not be any cover ups or brushing under the carpet . I was reading on PH and someone was mentioning how common the head gasket failure was becoming on the e46 M3. Looking specifically at the CSL though can I ask who has suffered or done a preventative gasket replacement. The poster mentioned seeing x3 CSLs in for head gaskets failures. I am guessing that heavily tracked cars are possibly more susceptible as well as higher mileage.

Perhaps a cut and paste with me to start. Feel free to bastardize my layout but was thinking Y/N or P - preventative with rough mileage and if it is tracked or not. You may also with to mention if you have had a compression test done.

So here goes me:

N 41,000 miles - tracked - no compression test (yet) - Pip

My warranty is about to expire so want a compression test. How much are they and where should I go?

You need a cylinder leakage test, not just a compression test.

Nothing going on here....move down the bus please (is there a members section?)

105k kilometers, tracked, ECU map stock, no HG failure. Leak test done twice.

My car is on 70k miles, I believe that it did have the head gasket done before my ownership. I assume it has been on the track, why else would somebody fit lovely big AP brakes?

Mine had the HG done at 75K as part of preventative maint.

No prior signs of failure but according to Barts, it couldn't have been any closer to potential disaster. Had split between cyls 1 & 2, 5 & 6

Tracked prior to me owning it but no idea how often.

Had my HG done at about 70k
went in for a service and Gareth at Elmes did the HG at the same time as he said it sounded funny but I didn't notice it, all sorted on warranty along with a new gear box. thanks very much

I tracked it a few times and don't think its had a particularly hard life before me.

If your compression test results are good, what issues would the leak-down test actually check/identify?
