Guest TurboSedan Posted November 30, 2004 Report Share Posted November 30, 2004 well i brought my TGP heads down to the machine shop today. i disassembled the heads myself a few days ago, and had all of the valvetrain parts in their own labled bags (1I,1E,2I,2E,etc,etc). i'm having the heads cleaned and bead blasted, new freeze plugs installed (one was leaking pretty bad), 3-angle valve job, checked for flatness and reassembled with new valve seals. i let them know that i really did not want the heads to be resurfaced if possible...i'm really hoping they don't need it. altogether it's going to be about $140. does that sound like a fair price? thanks Quote Link to comment Share on other sites More sharing options...

R Dubya Posted November 30, 2004 Report Share Posted November 30, 2004 That's a fair price. I took mine to the machinist when they were off the TGP and it usually runs about $200 for total teardown buildup. I got out of there for $300 even with the block honed, heads redone and damn did they look good. I took him the valve seals and cam bearings.

TGPilot Posted December 1, 2004 Report Share Posted December 1, 2004 Josh, Valve seals are one thing to have done...but valve guides should also be done at the same time. Machine shops normally charge between $6-8 per guide to have them installed. There is some machine work they need to do to get them in properly... 8) Quote Link to comment Share on other sites More sharing options...
GutlessSupreme Posted December 1, 2004 Report Share Posted December 1, 2004 (almost..) on the same topic: how much would it cost to have the block bored? I'd love to have a 3.2 turbo... Quote Link to comment Share on other sites More sharing options...

Guest TurboSedan Posted December 1, 2004 Report Share Posted December 1, 2004 (almost..) on the same topic: how much would it cost to have the block bored? I'd love to have a 3.2 turbo... i'd like to know this too. i have my TGP 'V' engine sitting on an engine stand tucked back in the corner of my garage right now. it has a melted piston and i believe it will need a .020 overbore....although the cylinder walls look perfect which is surprising considering the way the piston looks. after i get my 3.1 turbo 'T' engine done and installed in my Cutty the 'V' engine will be torn down and new Mahle pistons will be ordered for it (and many other things ). i don't really expect this 227,000 mile 'T' engine to last very long with 8psi being stuffed into it so i figure i should start on the 'V' engine rebuild straight away lol. it would be nice if i could get away with honing the 'V' block but i'll probably have to go .020 over.

TurboGTU Posted December 1, 2004 Report Share Posted December 1, 2004 I would stay away from Bronze guides on a turbo head. If theres alot of play..(i highly dout it)..then new valves. Usualy the exhaust valves are toast on the seat...so new valves are always a good Idea. Quote Link to comment Share on other sites More sharing options...
TurboGTU Posted December 1, 2004 Report Share Posted December 1, 2004 Cross your finger it doen't overheat one of thies days. :shock: The bronze will come loose or lock the valve in place. Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted December 1, 2004 Report Share Posted December 1, 2004 what kind of material would be better for valve guides? these heads 'only' have 111,000 miles on them, at least that's what the odometer read in the TSTE the engine came from. it's just that i'm on an extremely limited budget, it sounds like new guides are going to be another $75-$100.

Guest TurboSedan Posted December 1, 2004 Report Share Posted December 1, 2004 just dropped off the valve seals at the machine shop. the guy there didn't seem to think they would need to be replaced, but he would check them out to be sure.

R Dubya Posted December 1, 2004 Report Share Posted December 1, 2004 If you've got them, have them installed, just so you know they are new and they won't leak. Quote Link to comment Share on other sites More sharing options...
TurboGTU Posted December 2, 2004 Report Share Posted December 2, 2004 YOur using Viton seals right. Those are the good ones. I would think these heads would hardly ever need valve guides. Steel on steel. Other heads are steel to cast iron. I would highly dout they wear..if anything..just the valve steems..but like I said. theise turbo heads love to eat exhaust valves. New valves and your set. Quote Link to comment Share on other sites More sharing options...

Guest TurboSedan Posted January 4, 2005 Report Share Posted January 4, 2005 well i got the TGP heads back from the machine shop today. total - $191. this included: $2.68 - 4 expansion plugs $30.00 - surface both heads $144.00 - hot wash, bead blast, grind valves & seats and assemble heads $5.22 - service supplies $9.10 - tax the heads look excellent! they look practically brand new compared to when i brought them in. i talked to the machinist when i brought the heads in and told him i really didn't want the heads to be resurfaced if possible because the engine will be seeing ~10psi. he told me he just barely touched them so i'd have a good surface for the head gaskets to seal to. all in all i'm pretty happy about it. i just bolted the heads onto my 'T' engine tonight with new Fel-Pro head bolts & Fel-Pro 9471PT head gaskets. hopefully i'll have the rest of the valvetrain together tomarrow along with the lower intake and valve covers. i still gotta pick up my Melling 95HV oil pump and then i can get the rest of the motor together, bolt my new Luk clutch kit & 282 onto it and drop this sucker in my Cutlass ahhhh progress feels good.

R Dubya Posted January 7, 2005 Report Share Posted January 7, 2005 Sweet Josh.. get some pics up of them when you can. These are my heads when I got them back from RPM, the best machinist around here. [/img] I know I've posted these before but it's something to compare to. Now get to work putting it back together and get it running! $191 is a fair price too! I paid around $200 for mine then another $100 or so for the block work.. cam bearings, cleaning, etc. Quote Link to comment Share on other sites More sharing options...

R Dubya Posted January 25, 2005 Report Share Posted January 25, 2005 They look excellent. Nothing like the nice clean look of aluminum. They came out really good hope everything goes smooth. I have to go to the j/y this week and look for a few things, so I will look for that bracket. I have one but I will need it eventually.. but there is always a few new w-bodies everytime I go.

dbtk2 Posted January 25, 2005 Report Share Posted January 25, 2005 Those heads look really good. When I bought my 3100 heads on ebay they had been freshly rebuilt, so IMO I stole them at $110 for the pair becuase they been resurfaced, hot tanked, new valve seals, valve job, etc..., and they had beehive valve springs on them. So IMO I got a pretty good deal. But I would definately say you did not get a bad deal yourself. It looks like it was worth every penny of that $191 to me.
