That would be the cheapest option but....who knows how long the car would be off the road. 1 Link to comment Share on other sites More sharing options...

The problem existed before that already though. The replacement housing had been checked for operation. It had new shaft, bush & flapper installed plus the seat was machined 20 thou to ensure it didn't catch. It's a bit thin for seat on the top (probably 1.5mm) but seats perfectly. 1 Link to comment Share on other sites More sharing options...

I was told it was seated - no tight spots or anything.Where going to give it a break until after PowerCruise then depending on how much I'm up for already, get car in again. On the plus side, the car is making 362rwkw but I'd need to run it on the Bonneville salt flats to beat anyone. 1 Link to comment Share on other sites More sharing options...

I would have given up by now and put the stock snail back on, to see if the issue is still there. Surely that would rule the MTA out nooooooo? 1 Link to comment Share on other sites More sharing options...

I said to park it until after p/cruise.I may take the dump of myself or, borrow my mates snake camera and just drop the lower flange and have a look. Even just rattling it when cold will probably tell you if it's not seated. If it all of a sudden goes back another 5mm you'd know straight away.They did take the lid off again this morning and double check cam timing which was fine.Thanks for the help guys. I do appreciate it. It's 'just a car' and still drives, but it's our passion and hobby as well. Edited 06/09/14 03:17 AM by Bomber 3 Link to comment Share on other sites More sharing options...

This afternoon, I've secured yet another - this time unmodified FG housing, which I'll have just in case. I'm picking that up Monday. I'm not convinced there is a problem however the Engineer that reconditioned the current housing, did have to drop the seat because it was initially catching.Prior to my use and the new bush etc, it was supposedly working fine with a GTX3582R. It may have been but the amount of shaft play and that they'd left the boss in place running close to the flapper, required fixing. By setting the seat down 20 thou actually gave more of a seat too. At worse, I reckon it's got 1.5mm on the top then at least the same or a bit more for the remainder. I am a little concerned however, that it wasn't 'd' ported to ensure it's impossible for the flapper to grab.Anyhoo, lets see what it looks like. 2 Link to comment Share on other sites More sharing options...

This would give you a good 2 week holiday and you get to catch up with the guys in WA. 1 Link to comment Share on other sites More sharing options...
