Blown Head—how to repair?

[Quadcammer]

While it might be physically doable, id never do that. Just dropping it out is easier. These motors dont blow head gaskets so you likely have a cracked head

+1 to what Quadcammer said. I have not personally had one repaired, but I've heard that a good repair for a cracked head on one of these cars will cost about $1,500 - just the head if you remove it and send it out. One of the cars I bought had the full repair done by a shop about ten years ago. I'd have to find the receipt to be sure, but I think it was over $8,000 by the time it left the shop. You could probably find a warrantied used engine for about the same price and less hassle than the head repair.

I vote 3.6L

Welp. Thanks for the advice guys. Yeah I'm expecting to replace the head. If anybody has a 4-5-6 head laying around PM me!

I had already started preparing to pull the head in place. I figure that I've got nothing to lose. I if the head doesn't come off cleanly, I'll just slap back on what I need to and switch to pulling the engine. I'll post an update on how it works out. For the next sad sap.

I suspect that the problem will be removing the tappet cradle from the head... maybe there probably won't be enough space to get it out bc the chassis is right there. Everything else seems doable. Already have intake and exhausts off. Can set cam timing. Maybe torquing the head will be very awkward from down there too.

It`s definitely doable, once I pulled the head off of a Boxster in a junkyard. It`s not ideal though, but you have nothing to lose.. There are heads on ebay for a couple hundreds, just make sure you buy it together with the cover and camshaft shells, they are all line bored and numbered.

Much better to remove from the bottom.
