I am working on my TR and I am confused about something.
As far as I can see, I do not have the warm-up regulators on my '87 TR. I checked the workshop and parts manual, but as far as they show, every TR has warm-up regulators.
On the first picture I have circeled the places where the regulators should be (as per my opinion).
Amongst other things, the warm-up regulators (WUR) are controlled by the air presure of the air intake
manifold. Therefore there should be small hoses connected to the air intake manifolds and to the WUR's. On my car these hoses are cut off and closed with a screw (see picture 2 and 3 upper circles).
The WUR's should also be connected with 2 hoses to the trottle housing. On my car these hoses are also cut off and closed with a screw (pictures 2 and 3 lower circles).
The other remarkable thing on my car is that it has no catalytic converter, however it does have the 2 oxygen sensors in the muffler pipes. In other words, my TR has the original first type exhaust system with 2 oxygen sensors added.
This car has been imported in the past and it might be possible that it comes from Swiss where the emission regulations were different as in the rest of Europe at that time (as in the US). Maybe somebody imported it and removed some of this stuff, because it was not required any more?
Is there somebody who can help me with this puzzle?
(I have bought the car with a broken clutch and it has been standing still for 10 years, so I have not driven the car yet and therefore don't know wheter it runs well).
Also on some pictures of engine compartments on this forum, I saw that there are more TR's with no WUR's on the places as where they should be (e.g. the TR of Carguy). By these cars the small vacuum hoses that are connected to the front side of the intake manifolds (looking from the backside of the car) run to the right side of the engine compartment. Can anybody tell me where they are connected to?
So in summery I have the following questions:
1. Does every TR have WUR's?
2. If the WUR's are not as positioned as I mentioned above, then where should the small vacuumhoses from the inlet manifold be connected to?
I hope you guys can help me out over here.
