Cadillac Seville / Cadillac Eldorado Forum Discussion, Blown Head Gasket? how to check in Past Cadillac Vehicle Discussion; That link mentions a compression test. A compression test will not tell you if a HG is breached. A leak ...
I realize this is an old thread, but is this guy still in business? The weblink doesn't work anymore, unfortunately. I may be having an issue with my N*, and being in Michigan this would be doable for me. For my beater I just used some OTC product like this - http://store.gobluedevil.com/head-gasket-sealer-38386/ when the head gaskets went, but even though I had good luck with that it ain't coming near my Caddy. So, if this guy's no longer an option, any other recommendations in or around the Midwest?
Sorry, I'm an idiot with technology, this was in response to NoSaint55's post about the N* engine specialist in Ohio and the website at http://www.cadillac-doctor.com/
