project on hold Reply #451 – June 17, 2011, 08:18:56 AM Bad news. I've noticed water exiting the tailpipe and was hoping it wasn't a problem, BUT........ I pulled the rad cap and found goo.So I'm just gonna rip off the heads and go with some aluminum aftermarket ones. This will take a while since I need to save up for them first. Pretty depressing.

I don't remember if you'd had the intakes off, and I know you haven't really run the engine all that much. I'm sure you've thought about all of that, but just wanted to ask. Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #453 – June 17, 2011, 11:10:07 AM Just something to consider if you would like to delay the purchase of new heads: With stock heads and the turbo, you'll be at the limit of the block. Add a good set of aftermarket heads and you'll need to focus on how to limit the power to what it'd put out with stock heads...You may be better served by buying a good set of head gaskets & studs and make sure the heads are flat.The work you've put in is amazing and I know I'm not the only one who's enjoyed the chronicle. I'd hate to see you get snagged here and get pulled in another direction. I know it's happened to me (not that I'd listen...). Quote Selected

1988 TC single Holset turbo 5.0/ 4R70W Reply #455 – June 17, 2011, 04:59:52 PM You have put any serious boost to that engine yet have you? What caused the HGs to go?I would check your block for flatness before cranking on a new set of heads only to find out it was warped block to begin with. A head gasket set is only $81. Least that way you could be driving it while building funds those heads. (that and I want to see running now ) Quote Selected

Chuck, No not POSITIVE yet. I may be missing something. I didn't bolt on the heads myself. That was done before I got the engine in 'rebuilt' condition.I checked out the lower end and cam timing, all seemed well. I did do something that may have contributed. I changed to head studs after the intake was on. I pulled and replaced one bolt at a time. Maybe that caused the leak condition.At this point in time I can't go forward until I back up, though.

I'd hate to see you get snagged here and get pulled in another direction. I know it's happened to me (not that I'd listen...). True statement about the power capability. I have always planned to go to aftermarket heads. I'll be able to run lower boost to reach my goals with good heads. I just wanted to run it this way for a year first.I am still mulling over what to do. I suppose I won't really know until I yank the heads. I have an extra set here rebuilt with valves and springs that a friend gave me in trade for my used GT40P heads. I'll check them for straightness and possibly go that route as a quicker solution.I appreciate your input. Quote Selected

Least that way you could be driving it while building funds those heads. (that and I want to see running now ) Nope. It hasn't seen an ounce of boost.Good advice. I'll for sure check out the block and head surface really well when the heads come off. I noticed the water out the tailpipe a few runs ago and have been dreading that there is a real problem here. It is one reason I've been dragging my feet a bit lately. It makes me a bit sick to think of undoing so much. I'll need to get it torn down soon, though. I will need to know what is up.

1988 TC single Holset turbo 5.0/ 4R70W Reply #460 – June 21, 2011, 09:44:06 PM I haven't cracked into the head issue yet, but pulled out the hood and tried to see if it fit. It will work if i cut back the inlet on the pass. side scoop after removing all the sound deadener and plastic from the turbo air inlet.I also have enough clearance to go with TFS TW 170 heads in the future with a 3/8" spacer on the upper intake. That was why the hood went on now.I feel better about a stop-gap solution at this point. Quote Selected

How does the oil look?I have been dragging my feet too. Probably because it is too hot to work on the car right now.But don't loose heart! I'm counting on you to finish this thing. :) Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #463 – June 22, 2011, 09:36:55 PM Thanks for the support westie. I'll keep at it. Just taking a 'breather' right now.Don't worry, Shredder! I got a confidence little boost recently from an unexpected source.A customer from my TR6 restoration days called up out of the blue. I haven't talked to him in 10 years at least. Did him a REAL nice Pimento red TR6 back in '95. He says to expect a call from a guy in Austin, TX who bought the car. Said he got an offer he couldn't refuse and the car is sold.Well, the new owner calls last night. He wanted to thank me for building such a nice car! He said the paint is an 8 out of 10 after all these years, and he drove it 27 hrs. from Michigan to Texas without a hiccup. I went back into my old photo albums of all the cars I've done, and after a while I was feeling better about knocking this project out as well!I just needed to step away for a bit is all.

1988 TC single Holset turbo 5.0/ 4R70W Reply #464 – June 24, 2011, 02:32:56 PM Well congratulations on having TWO happy TR6 owners! That was a nice shot in the proverbial arm. Pls share pictures of the TR6 if you have some.If you do have HG issues, just use your ready to run E7 heads for now. Many guys have made great HP with a turbo on those heads. Obviously, the more intake volume under the valve is better, but with boost, you will be surpised.As you know, I plan to build my TC in stages, so I can at least DRIVE it for a little while between stages - to work out bugs and such. With how in-depth your build is, I'd recommend the same approach. But nice Aluminum heads would be nice! :) Quote Selected
