NIce work! How many hours do you think you put into it?

Was there any concern with machining the heads a second time?

Around 25 hrs.
The first time was a 92L w/217K. I didn't machine the heads that time. No problems. The Second time was a 94LS w/187K. I didnt machine the heads this time either. No problems.

Jetdoc,

Did you over-torque the head bolts (as has been mentioned several times) on this car?

A week ago I decided to man-up and replace the seeping head gaskets on my Legend. Keep in mind that the most car work I've done myself was change the oil / spark plugs and such, so my mechanical skills aren't the greatest. But I do own a 251 piece Craftsman set of tools and I can't afford to pay the $1000 to $1500 price quote that most shops charge for this job. Thus, I began to do the whole thing myself.

Today, I'm about ready to put my heads back on, the only thing holding me back is replacing one knock sensor (If anyone has one PM me ASAP and can someone tell me what size of wrench I need to take off the broken knock sensor with, I'm guessing 26 or 27 mm).

As Swift suggested I am using RL gaskets and I intend to re-torque them to 62 pounds (any other suggestions welcome). I had the gaskets replaced about a year ago but I made a mistake of not using OEM gaskets so here is the price to pay for that. Also, someone asked about resurfacing the heads twice; I've just done that without a problem.

Yes, I torqued them to 62 ft lbs.

An adjustable wrench works fine.

Did you torque the non OEM gaskets to 62 pounds when you did it the first HG job? Just wondering if you had used OEM but not torqued it to 62 pounds, if they would have still blown.

I remember I had them torqued to at leased 58 pounds maybe more, the first time around. However, considering everything was done perfectly and there was nothing else that could have gone wrong, the only logical conclusion is that the head gaskets were of poor quality. This was supported by the fact that they (gaskets) were falling apart at the seams, so to speak, when I took them off the block.

Thanks for the confirmation on that, JetDoc. I'm going to be doing the same on mine.

Socol - you mentioned using RL gaskets (as recommended by swift)? I did (several) searches and couldn't find the proper combination that would yield any thread where this was discussed for the 2nd-gens. Can you point me to this discussion? I'm going to use OEM head gaskets as of right now....just curious if the RL gaskets are that much better.... I don't want to be doing this twice.

Thanks guys - this is a great thread.

Wasn't much of a discussion, and looks like you've read that thread before.

Side note: You'll need more things then I mentioned in that thread, Cam Seals come to mind...

Thanks Socol. Yeah, I remember that thread... I was hoping there was more to the discussion than just that. Thanks for the reply, though.

Do you know any data that suggests the 3.5L gaskets to be better? I've got the OEM gaskets ready to go on now, but I'd spring for a set of 3.5's if it'll keep this from happening again. I'm just a bit apprehensive since this topic (BHG) has been around for a long time, and there's not much evidence (other than what Swift says) on the forum to suggest that the 3.5 gasket is a definite fix.

Has your experience shown the 3.5 gaskets to be a direct fit?

Well here is my logic behind using RL head gaskets; they were made for the more "advanced" C series engine; more "advances" aspects in the BHG realm include:

from what I understand the torque on RL heads is higher so I'm sure the head gasket was "reengineered" to some extent in order to comply with the added pressure. And last of all, and probably the biggest reason why I went with RL gaskets was simply because I felt like trying something new and maybe, possibly, hopefully, better. I'm curious what Mike Diaz would say about the RL gaskets.

Forgot to mention that from my not so expert opinion, the RL head gaskets fit perfectly.

RL and Legend gaskets look exactly the same to me. I don't think there's any difference between the two.
