Great work. I too have a 1970 TR6 PI. This was sold new here in early 1971. There were quite a few that came here (New Zealand) '69-'75. They were all PI's. Same spec as the UK.

Back in the day my father had a few 2.5pi big saloons. Lead from the leaded fuel used in the UK in that time was the cause of some issues with the Pi system. The remedy was to drive the car hard, revving it to the red line! I remember my father being so happy when the engine ran like it was supposed to again.

There is a guy in the UK who has designed a much improved PI throttle linkage. It uses bearings instead of crappy nylon bushes and has much more adjustability. Installed it on mine and I'm happy with it.

As said I'd be tempted if there is no play in the spindles to have left the crud in place as it provided a good seal. If there is play in the shafts might be worth having the bodies machined to take some sealed bearings which will get rid of the play and improve the balance/response set up across all three units. To replace the crud spray the inlets with MolyKote which will improve the initial seal until the carbon/varnish builds back up. I'd recommend having a go with the DIY plating it's fun and satisfying seeing everything return to like new. Keep it coming!
@cheftush
@cheftush Жыл бұрын
The only thing that I’m concerned about with the diy plating is the space it takes up…space is at a premium in my garage….even if I were to do a small bucket set up, I’d really have no where to set it up and store it afterwards….

The cross shape in the nylon bushes for the injectors was introduced in an attempt to reduce heat soak from the throttle bodies to the injectors to try and minimise fuel vaporising in the injectors which subsequently created starting problems, due to air in the injector and hose. The cut away just reduces the contact area

Great work on the cleaning Dave and after I had cleaned the butterfly’s on my TR5 it was suggested that it would have been better to leave than dirty because of the seal issue and I have to confess she runs better tha more I use it…… so good advice from Steve and just in time.

Wow this is going to be an interesting project Tush, they cleaned up well. my concern would be if they stay that clean for two years of storage if not clear coated. Looking forward to your next project TR3. Thanks agin for sharing your experiences, I’ve learned a lot over the past few years, that’s helped me with 1962 TR4. Got it running but having a tough time getting it to run smoothly with the webers and prextronix. But about a month ago I drove that car down the street and back. Thrilling to have that move under its own power for the first time in 40 plus years. Cheers !

The nylon bushes that support the injectors are basically a push fit into the throttle bodies, each one has an O ring on. So if you wish you can remove and refit these when you refinish the bodies. I expect you will find the housing in the throttle bodies to be identical (and not related to the difference in injectors you are seeing). All of mine were push fit injectors and all have the cross shape when viewed end on.

Could that PI set up bolt on to a carbureted TR6 engine? Same camshaft?
@cheftush
@cheftush Жыл бұрын
It’s a different camshaft for the PI set up….I’m actually running the PI Cam in my TR250 with carburetors though so it could be done technically as long as you had all the proper bits. For example, a North American carbureted TR6 gas tank is different from the PI tank as there are return lines to the tank at the top for Injected cars among other things.

Hello Dave. I haven’t chatted with you for ages. Off the topic I was wondering since G4 ??? Trans fluid is hard to find. Or at least for me. My TR6 is a 4 speed. Do you use straight 30 motor oil or 5w30 motor oil in your overdrive trains ?
@cheftush
@cheftush Жыл бұрын
Hi Doug, yes in my overdrive transmissions, I use SAE30, non detergent oil. 4 the 4 speed, you can use GL4 gear oil from Miller Oil, Sta Lube, or Penn if you can find it. You might have more success finding Redline MT90 Gear Oil as this can usually be found through places like Amazon if you can’t find it locally.
