The Griff windscreen has a rather nasty crack in it. I need a new one but looking at the seals for where the roof fits and other areas it looks like a job for someone who knows what they are doing. It is very neat and leak free at the moment and I would like to keep it that way.

Also my exhaust manifold has cracked around one of the pipes at the pint where the pipe connects to a flange which bolts to the block. I had them welded up recently, is it just a case of doing them a few times until they are good or am I wasting my time trying to repair them a second time and should I bite the bullet and buy some new stainless ones?

Any recommendations or warnings, feel free to pm or email me with comments if you don't want to put them on here.

Cheers

Richard

There have been a few sets of manifolds up fore sale recently for the Chimp/Grief.

I would buy a new s/steel set with 500 headers, check the fit and then get them ceramic coated.

Glassman on here is very good at fitting screens. I think he his North London based.

Will your insurance cover it given the crack? I had mine done by auto glass last year. In the end they did a good job but initially insisted on trying a aftermarket screen, which was never going to fit well. Once I’d pushed for an original tvr screen i had to wait Two or three weeks (pretty much the entire Scottish summer) for them to get it and get it fitted - apparently only certain fitters can do it and they won’t book them until the screen is in stock.

If you buy a second hand manifold be sure to ask the seller to fill it with water first, easy to do, you just turn it so that all the holes are pointing upward. That will show if there's any failure at the 4 into 1 junction. Many are failing there and more so on the 'used' market as removal and storage can cause these poor internal welds to fracture.

Alternatively you can cut a section out just in front of the precat at the bottom where it is out of sight. Internal welds can be repaired through that access hole

The car is a pre-cat with a 4.5 BV engine, the manifolds are the originals (I think).

It's the joint where the pipe meets the flange on the side of the block.

The car has spent the last ten years in virtual storage, i.e. it did a run to the MOT station and a few short runs each year (just a few miles each time). After a few long runs I had a number of fractures around these joints. I had them removed and re-welded and all was good for about 600 miles. However yesterday it did a 300 mile run, some of it at quite reasonable speed (i.e. considerably faster and further than it has been driven for the last ten years. I think I probably heated them up MUCH hotter than they have been for many years.

The result was a large fracture on the most forward pipe joint on the left side of the block. It could be welded in position but I would not want to risk the possibility of damaging the ECU and would therefore have it removed to weld.

What I guess I am trying to decide is that after a few such runs and repairs will it be reliable or is the metal in such poor condition that it's not worth spending money repairing?

The insurance would probably cover it but I am don't want an aftermarket screen fitted and have heard a few horror stories about damaged paint, damaged leather and sealent everywhere so I am thinking I may finance it myself to make sure the job is done properly from the start. its good to hear that you managed to eventually get yours fixed via the insurance with an original screen.

Autoglass did a fine job on my Tamora - insurance job.

That said, I'm considering fitting heated screens to the T cars. One of many jobs D:

I'm sure I've read that you can specify a specialist to do your windscreen replacement on insurance policies and not just go with their recommend suppler. Certainly worth a call or a read of your policy document.

Had same concerns when replacing the windscreen on my Griff last year. My insurer (FJ) allowed me to choose my own repairer for additional £100, which I felt was cheap if it meant it was repaired by someone who knew what they were doing!! I took mine to Heath at XWorks. He did a great job and even sent me pics as the job was been done. Would highly recommend him.

I have just had the screen replaced by Heath at X-Works.

Classicline were very helpful when I explained that I had read so many horror stories about National Windscreens and would prefer the job to be done by an expert.

Heath gave me a quote, Classiclines underwriters approved it and I got the job done. I had to pay for the work up front and send the invoice to Classic line for a refund minus the excess.

X-Works also welded up the manifold and it was all done in time for me to make the Beaulieu supercar weekend.

A thumbs up for Classicline and X-Works from me.
