Troubles again

I know this is a Land Rover forum but i ussually get some good quick responsos from you guys

so to increase my chances of fixing the zook i am posting on here as well.

Ok so here is my dilemma yesterday morning a mate laid it on its left side i pulled in back onto its wheels and to be extra careful left it for 4 hours (guessing thats plenty of time) then checked all off the fluids prior to starting it they were all fine. At first it started and ran rough but after a few revs it cleared the cob webs and was running like always

so we decided to take it for another run i was driveing it on a very basic flat track with some rocks i got a hole in the exhaust and kept going then after a while it wouldn't idle and now it surges when driveing. I have drained the carby any other ideas?

Cheers! And you will all be glad to know it is always the Disco that saves the day, as fun as the zook is the Landy just crawls easily to what ever stupid track the zook is stuck on

Cheers! hope to hear from yas!

You haven't blocked the exhaust or restricted it in anyway?.VW flat fours won't run with a hole in the exhaust,maybe the zook is the same?. Pat

It has a hole in the exhaust but thats all i can see, it will kick over with some throttle and then you need to keep it reving to keep it running and even then it is rough.

I will check more of the exhaust.

There is a hole in the exhaust and there is a dent in it as well. Nothing i would consider to dramatic

A VW will go without an exhaust, well mine has plenty of times, just not with a squashed muffler.

Perhaps you have restricted the air flow too much as suggested.

But if it were that why would it run and just not idle? i have tried increasing the idle. What trouble could of the lay over played in this issue?

**Grover-98** · 3rd February 2009, 11:48 AM

I just set the idle to about 1100rpm and it started first go and the idled for around 2min before dieing i didn't rev it and it did not require and throttle to get it started. Could the hole in the exhaust be causing turbulence hence it will not hold a constant rpm rather it rises and falls between around a gap of 200rpm?

If this is the problem should i just cut the exhaust before the hole as it is only a bush basher i the hole is at the join to the back of the muffler.

By the length of time it idled and the fact that it will drive i know its not a spark issue or nor is it a fuel issue

I am in no way an expert in such matters but sometimes the back pressure created by the exhaust system can be crucial to an engines performance, (well it made about two gears difference to a V8 diesel Merc.) so depending on where you have holed the exhaust system there is a possibility that your problem could lie in these realms. Perhaps if you simply plate the hole (coke can) and see if it makes a difference. Has the pipe been crimped further along the system.

Yeah just cut the exhaust off anyway you don't need it

**Grover-98** · 3rd February 2009, 12:14 PM

I'v heard that holes in exhaust can cause "turbulence" would someone be able to explain to me what this means and im guessing that could be what it is as i have checked everything else and it will idle now for a fair while and will rev fine but flutters a little. I am suspecting now it could be due to the hole in the exhaust which i did whilst i was driving over the rocks.

Cheers!
