1988 TC single Holset turbo 5.0/ 4R70W Reply #1007 – December 16, 2013, 12:52:26 PM Well, I have my proposed evac system diagrammed. It SHOULD work in two ways:First, under normal cruising and idling, the PCV system will route as normal EXCEPT through an additional supplemental oil separator to cut down on what the upper intake sees now.Second, when vacuum is low in the intake (or when in boost), the exhaust venturi scavenge system will take over and route the blow-by fumes to a second separator and out through the exhaust pipe. Ideally I should always maintain a vacuum on the crankcase at all times, regulated by the pcv system or a 10"hg limiter valve on the exhaust side. Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #1008 – December 16, 2013, 08:29:13 PM That Fel-Pro MS 95952 intake gasket set should work fine with your heads. It lined up great with the intake ports on my Edelbrock heads. The ports are the same size as the Fel-Pro 1250 gasket but they are not made of paper like the 1250. The 1250s have a tendency to leak as the paper degrades from engine coolant. No cool. Quote Selected

The last set looked good after being run for a couple years on the iron heads. Like you say the composite gasket seems to be a good choice. Quote Selected

I still have a full sized wired keyboard in the car for tuning MS or web searches, I will be replacing that with a smaller wireless one someday.Now that the windows tablets are cheaper I would probably just go with one of those in a future build.The only disappointments in it so far is that my phone can't be used through the pc, and my backup camera is a bit flakey. I bought the cheapest one of those, so that may be the issue there. The phone I bought a hands-free solution for after spending months trying to come up with something that would work. Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #1012 – December 19, 2013, 11:07:36 PM When I unbolted the headers I was disappointed (pissed off actually) to see that the drivers side header was loose on the front port. It had been leaking and I could hear that I had a leak. I had used some expensive Percy's locking header bolts on it. They have now been kicked to the curb. I don't trust 'em in aluminum heads when they aren't holding in steel.I see I have a little 'rock' in the header , meaning that it is slightly bowed. So, I'm gonna cut the web in between the front and rear ports on both headers before I offer them up again. This time I will be using a set of Nord-lock washers under a set of 12 point 3/8 head ARP bolts. Maybe just a dab of blue loctite for good measure.I also have trouble keeping my valve covers torqued down. They always want to loosen up on me. I'm still figuring what I am going to do about that. Maybe go to studs with a dab of blue on those too. Leaky cars suck. Oil fires are dangerous.Nord-lock video: https://www.youtube.com/watch?v=mgwmuZuJ02I Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #1013 – December 20, 2013, 02:21:13 PM OK, ordered all the final parts to re-assemble this thing.1" Proform #66753 wedge locking header bolts. I had to get 2 sets of 12 since the 16 pack only comes in 3/4"L. That kinda sucked. I want the extra length going into aluminum with the thick s on these headers.I considered SS studs, but at $145.00 a set was put off by the price, and I wanted a wedge lock washer which the ARP doesn't have. I got Trick Flow valve cover studs with 12 point black oxide nuts and ordered a package of 20 Nord lock washers to hold those. I have an air injection check valve from the Explorer engine to use for the venturi evacuation system, so I ordered a pair of Edelbrock breathers and a Vibrant Performance scavange pipe that comes with a weld on bung and threaded pipe. Rounding up that system is a (hopefully) suitable vacuum limit valve from Zoro Tools (I got the Nord lock washers from them, too)Finally, since the car is into stage 2 of power production with these heads I decided to upgrade injectors. I intend to shoot for under 500 HP, so I found a good deal on modified Bosch injectors. They are EV6 style with an EV1 connector and flow 48 lbs.@ 43.5 psi. http://fuelinjectorconnection.com/shop/viewitem.php?productid=409So, I figure at a 39 psi base pressure they should flow about 46 lbs/hr, which gets me to 500 HP at just over 85% duty cycle. The nice thing about the EV6 injector is the flow pattern is better and the pintle mass is less so they work faster than a similarly sized EV1 high-z injector. My 255 lph tank pump and lines should be sufficient at this HP.I can sell off my recently cleaned and flow-matched brown tops to someone looking to stay under 400 HP turbo/supercharged or 500 HP N/A.If anyone here is interested let me know. Just remember these are LOW IMPEDANCE injectors and need a resistor pack or suitable ECU to run them. They are the stock injectors for a Thunderbird 2.3 turbo. I'll list them in the classifieds when I get the new ones in hand. Quote Selected

They are steel core and they don't compress. The bolts stay tight and the gaskets have yet to leak on me. Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #1015 – December 20, 2013, 04:32:14 PM Thanks for the tip. I went through this on my 2.3's until I found "THE" gasket that worked.I just looked at mine and they are compressed. They are rubber, Fel-pro I believe.36.00 through Summit. Dang, the 351 guys have to pay 89.00 for a pair! Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #1016 – December 21, 2013, 12:28:21 PM That's odd. The 302/351W share the same valve cover gasket as they have the same heads. Perhaps the 351C covers cost more.Back to the FRPP gaskets. I didn't realize they were $36. I think I paid less than $30 for them several years ago. They are worth it though. Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #1017 – December 22, 2013, 12:32:11 AM Right-o. That has to be for the 351C.If it works it's worth it. Thanks again for the tip. Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #1018 – December 22, 2013, 12:53:58 AM Got the heads pulled, now tomorrow I'll clean everything up and check the block for flatness before I offer up the aluminum heads for the PTV and rocker geometry checks. It looks like the header wrap is killing my hotside. It's just allowing rust to form in a definite pattern underneath it. The unwrapped crossover looks 10 times better than the pieces with wrap. Soooooo, I am going to try the DIY Techline header spray on coating after I blast the parts and clean them. It looks like the silver is the best at corrosion resistance, and the black is best for a heat barrier. I'm going with silver and will see how it works out. I know the wrap is not going back on anything down low or that gets real hot. Those parts were affected the most. I might use some on the upper downpipe and on the wastegate tube. Those showed no signs of excessive rusting.I'd like to think that this time I'll have most all the bugs worked out of the combo for the long term. I want to get the A/C functional this winter after all this is done so it'll be ready for next summer. That'll mean making custom lines, some fittings, and just hooking up wiring I already have in place. I still need to do gears, axles, a good driveshaft and a good converter before it can be unleashed at the track. Quote Selected
1988 TC single Holset turbo 5.0/ 4R70W Reply #1019 – December 22, 2013, 10:05:51 AM Hey JimIm only wrapping the downpipe for that reason...just holds too much heat...causing warping...and metal fatigue.Going to be hot under the hood. But cant be helped.Travis Quote Selected
