M127 leaking after new head and gasket
My shop rebuilt the head on my 220seb and it is again leaking in essentially the same spot. I read through the old posts on the W113 archive about similar issues on Pagodas and the various remedies and work arounds tried. I would like to know if anyone has an update or more recent experience regarding the causes, potential remedies and so on. Also, when a head gasket is being replaced, is it common or even expected for the shop to plane or square the mating surface on the block or is that only done on a full engine tear down? I know they are supposed to check that it's square, but if not what is the procedure to correct when only doing a head gasket job? We are going to verify the leak isn't from somewhere else and migrating along the mating line, but if it is still leaking I'd welcome your opinions.

Wow, sorry to hear about that. Very frustrating.
During a head gasket change, a good shop will check the flatness of the block and the head, and adjust them as needed. I think the block may have to be machined outside of the car, but others can weigh in on that. All of this is an opportunity for a shop to make more money, so it would seem odd that a shop would skip these steps. If it isn't itemized on your bill, I would just ask them what specifically they did. If they didn't do something, they should be able to explain why. Good luck!

I see he has already replied to my post on Pagoda site on the subject, and has definitely been a great resource so far. Thanks for the recommendation!

you should have asked for a rebate and check your car again.
we had the same issue with my uncle's car when an auto shop replaced his tire with a new one. when he was test driving.... all of a sudden then tire loosen up and was detached from the car. fortunately my uncle was driving not too fast. but the autopartswarehouse shop did pay all damages Last edited by Downy_Marie8; 03-12-2015 at 10:30 PM. |

If the deck surface (or head) is damaged by scraping head gasket material it can cause leaks and blown gaskets. The surface is machined to a specific "RA" (roughness average) to enable the head gasket to properly seal. Many pros recomend the head(s) and block be resurfaced when ever the head is removed but that would require a total engine teardown.

All good now folks, it turned out to be a pinhole leak in the pipe coming from the head just above the gasket line but took heat and pressurization to show itself. Thanks for your collective advice!
