As I posted in the racing forum, the head gasket in my '87 3.8L Thunderbird took it's ball and went home during the first event of the day - skidpad. :(
At a minimum, the head gaskets need replacing. Engine has 262k miles on it. Timing cover also needs a reseal -leaking coolant. While I'm at it, might as well throw in a oil pump repair kit (http://"http://www.rockauto.com/catalog/x,carcode,1140220,parttype,5584"). Valve seals? Anything else I should probably do while I'm in there?
If I was going to pull an engine personally I would throw in a 5.0. It may be out of budget for what you want to spend but if you are going to pull an engine why not? Idk just what I would personally do. But if you wanna keep the 3.8 I would rebuild the engine. The rings have to be worn out and all the bearing are probably shot just because of the high mileage. It would be well worth your while and very beneficial.
Sounds like a good excuse to finish the split port swap...
This, plus a good rebuild, and possibly some manner of working the heads to help stop future HG failures? Newer heads an option? I know you did/are doing a new engine swap (I think that it was you..???) but would the newer heads be better? O ringing them even?
Not sharp on the 3.8 stuff, despite having three cars with the 6 motor.
Multi-Layer steel head gaskets and new TTY bolts. End of problem.
I've thought about throwing in a 5.0. At this point, I sorta want to see how far the 3.8 can make it before she grenades. 300k would be nice. :hick:
My original upgrade plan for the T-bird was to install a T5, then a 5.0, then a built 347. My new plan is to install a T5, but wait a big longer (for funds to accumulate) and swap in a Coyote +T56 (with my current rate of progress, 2035 ;)) New HGs, timing chain reseal, oil pump repair is <$100 and not too big of a project compared to a 5.0 swap. If the 3.8 gives up the ghost before the Coyote is ready, I'll throw in a 5.0.
The Split Port and 4R70W are in my '85 Cougar. Still sitting neglected in my garage. :(
I don't think newer heads are an option, as 88+ heads have injector holes in them. My '87 has CFI. Hopefully my heads don't have any cracks in them. Don't want to deal with used heads since they're so pr0ne to cracking. Would need to rebuild the engine to make rebuilt heads make any sense. At that point, would just go ahead with a 5.0.
Not sure MLS gaskets are available for '87 3.8s. I think Ford started using them in 1999 for the 3.8L. But even if they were available, I'd have to have the head/block resurfaced to a very smooth finish to keep the MLS from 'tearing' on the rough factory finish. If the block is coming out, something is going in. ;)
