First day of real TVR ownership - photos and questions
Discussion
Well it looks good from this angle (and most others): https://picasaweb.google.com/115660383436295169415...
It was huge fun on the test drive in the wet. I can see why side visibility is important when driving around in the damp. How twitchy is the back end in the wet!?! Three power slides on the same round about.
Couple of questions though.
1) It has been converted to carbs and it didn't like idling when cold although seemed okay when warmed up. Is this normal? Is this acceptable? Do I have to get used to the engine cutting out everytime I stop unless I sit there blipping the throttle?
2) It smells really rich, enough to make you giddy when stationary. Is this related to the pipe in the picture below which gentle smokes when the engine is running? Is there anything I can do about it?
3) How do I stop giggling when I drive it?
Hi Mate..I could be wrong but..
1.If its been converted to carbs then they should have been set up and it sounds like they havent..Also it should have a manual choke and shouldnt cut out ..Does this happen when its warm?
2.Im not sure what that is..It looks like a crankcase breather and im not sure if you can blank it off..It will probably suck air in on de-acceleration?..I think..
3.You cant..Thats one of the drawbacks with owning a TVR..Its like the joker in batman..The smile will become permanent.

Choke! I had forgotten about chokes . The last time I saw a car with a choke was my mums Fiat Panda. I will look for something that looks like a choke.
I will divert the pipe towards the chassis.
Perhaps with the choke set correctly and the fumes going under the car it will smell less. I suspect it is still running a bit rich but I will see.
Thanks so far. Please keep checking this thread as I will have more questions I am sure.
Chimeras are a bit more pricy...

pipe = crank ventilation. I'd put a filter or something on that. It's supposed to go on the intake manifold. That way the fumes can escape to keep it from pressurising and the oil doesn't leak out (cause it goes into the engine if spewed out and gets burned). Also a reason for oil loss those things.
You can get little round filters from car stores to put on it so it can ventilate but not dump your oil. Since it won't work with this carb conversion i reckon.
Why'd the prev. owner convert it to carb anyway?
Looks like a cool wedge though!

Exciting times - My first problem fixed!
I went to start the car again to move it and it was totally dead. No electrics at all. Traced to a broken battery terminal connector. This is now fixed.
I feel like a REAL TVR owner now..
.. and I have just gone back out to find my friends child 'just leant' against the headlight when it was up and not it is down. Great for attracting attention these cars.
Is there a clip or something that holds the light pod to the motor that he has broken? It is not easy to see how to get to the pods to look.
Also, when I turn the ignition on there is a loud wining coming from somewhere behind me. Stood outside it is behind the drivers wheel arch. Sounds like a pump but surprisingly loud

They probably converted to a carb because usually its a more reliable set up than fuel injection. That pipe you are talking about is the oil breather and on the fuel injection system it's meant to go back into the engine and burn back out of the exhaust. However when I bought my car that it was disconnected and only had a small filter fitted on top of the rocker cover. This made a lot of oil fumes enter the cabin, enough to make you dizzy. I could have connected this back up to the plenum but I chose not to as the car had been precision tuned without this, and could effect the running as the mixture would change. So what I did instead, I fitted a 'flame trap' and a length of pipe to run right to the front and under the car. This way the gauze inside the flame trap condenses the fumes and any oil goes back into the crank case and the fumes escape out to the front of the car. Now I can't smell the oil fumes and the engine can still breath. This open circuit does not actually effect the running of the car. In your case you already have a flame trap on there, so just fit a longer pipe to run to the front under part of the car. Just check that there is a metal gauze inside the flame trap so that the oil fumes can condense and run back into the engine. In my opinion you don't need to fit a filter onto the end of the long pipe to catch the oil as long as the gauze is in place inside the flame trap there won't be any oil to catch.

I will try and check out the fuel pump (somehow). That was sort of my guess as it seemed to come from that area.
I see what you mean about the noses. Mine doesn't have the black rubber.
Added a few pictures showing the interior as I extracted it to clean it. I am now on first name terms with the guy who built it, Steve is scrawled on the back of one panel. Also, I never realised that the radio was the only thing holding the entire centre tunnel trim in place ;-)
I assume to put the steering wheel the right way up I just undo the big bolt in the middle? Actually, after driving around in the wet earlier I think it spends most of the time on opposite lock!

That pipe is part of the crank case, PCV system.
Rover V8's REALLY need that to be set up properly. Every Rover V8 I've seen that has had the PCV system mucked about with ends up consuming oil and/or throwing it up out the breathers, rocker covers etc.
There should be a PCV port on the carb somewhere you can route that to. At least you can drill a hole on the base of the pancake filter and feed it in there. At least then it's consuming its own gasses.
Never understood why people convert these cars to carburettors. The flapper EFI system is relatively simple and pretty reliable. Ideally a carb fed engine needs a different cam to an EFI engine too.
Anyhow, at least carbs are easy to tune, so I'd get an exhaust gas analyser on it and check the mixture (they're almost always too rich).
Also check the ignition timing, those two things will probably make a world of difference!
If you're looking at a TVR as a donor, go back a few threads and look at the link I posted entitled 'how many times has this been for sale?'.
There has been a series 1 350i appearing on e-bay about 4 times and not selling. It's a right old shed but would make a good donor car, especially as this one seems quite tidy.
Good look with it!

the front end looks good. You need a big TVR on the front.I also have a carb setup. The sliced pipe in you pic should be attached to the PCV valve on your carb or on the air filter if there's an outlet. Without the connection you will get a negative build up of oil pressure resulting in a blown crankcase seal which is an engine out job to fix. By the way your car be the same one featured in this clip from you tube:http://www.youtube.com/watch?v=yY93C-YOay0
Hope you get it sorted...

GV. I don't understand why this would happen, as the rocker cover already is open on the other rocker cover by a small breather with a filter on it. So if the end of the flame trap is left open there should be no problem with pressure build up, as long as the oil is not lost, because it condenses in the wire mesh inside the flame trap and falls back into the engine. Why would there be a negative pressure build up? My car has been like it for a long time and there has been no problems. If the pipe is fed into the plenum as it left the factory then all it does is just burn in the engine and out the exhaust. Pressure should not play any part in this.
