Second that it's a diesel not a spark plug job. I'd avoid that mechanic in future.

Really need some weight behind it to make it loud. It was alot louder up hills towing a caravan on our last trip. Most of the video is full throttle holding it back with the brakes. http://youtu.be/bFU5hwe4HkU

It had the bypass pipe in for over 20k. The noise came with the intercooler kit.

All the piping has the lips to clamp to. TBH I was thinking more along the lines of a manufacturing fault in the cooler. I'll just take it to work one afternoon and pump 20psi up it. Hopefully come across something.

It's a factory snorkel. I'll have a look in the snorkel sometime could be an answer there. Don't think it's a leak it comes on mainly going up hills towing there will be a minor noise at around 3200 then it'll get gradually louder as you get closer to 2800 where it peaks. This all happens worst...

This isn't the first diesel car I've owned everyone neither am I inexperienced in this field. Diesel engines are all I work on. If I thought it couldn't be changed I wouldn't be on this forum. So please if you have a genuine opinion or information to share I'd appreciate it if it is a smart...

Thanks to everyone who answered my question and particularly the ones that didn't need to be smart. I've got the turbo timer and a forefront intercooler. I'll look into getting a sock now. The next noisy part is the intercooler. Works great with keeping the egts under control but the noise is...

It's running 14psi. I've had 3 different air filters in it the last one new and yeah I tried without the snorkel head it made no difference. I'll look into a sock for it for now. Just didn't want to introduce any more restrictions if I could help it.

Not much fun towing in 4th all day with a car as noisy as one of these things.

From what I can tell these engines suffer from premature turbo failure regularly and are known for breathing fairly heavy. I may be wrong but it seems as though they run rather lean and the 15psi is overkill and for egr purposes more then anything. If that is the case then provided the egt temps...

Hi all, I've been looking for ways to quieten down the intake on my zd30 and short of taking off the snorkel the only option I can think of is dropping the boost pressure. I realise it still won't be quiet but it should be a lot better then standard. The other possible benefit to this is the...

Which seal was perished? I thought the important seal was on the filter itself.

I've put the forefront winch kit in. Main difference I've noticed is it takes slightly longer to boost. There's no actual drop in pressure. Still pulls as quick if not faster. EGT temps are around 350-400 pre turbo at 100. Can still get them up above 600 but it pulls longer before they get...

Hi there, just wondering if anyone on here is using an AFR gauge. Tia

Haven't done a zd30 but everything else I've ever seen didn't matter as there is an open space inside the fitting in the line. The bolt will feed into the same open space no matter what way it goes on.

Egt gauge with a programmable alarm like an auber instruments to keep an eye on it while towing.

Hi all, been looking around lately for intake precleaners which mount on top of the snorkel in place of the ram head. I was wondering if anyone could comment on how well they actually work. Interested in two particular types, the age old Donaldson clear bowl which holds it's captured debris and...

Just curious rumpig what brand int air temp gauge have you got and how much did it set you back?

Found the prob. Broken return wires in both iat and boost sensor wiring. Maybe they're connected somewhere? Well I bodgied up a fix to test it out and let's just say it goes better.... Got to 145 with the pyro reading 750. Still had a lot more to go so I might have to get an alarming pyro with...

At first I thought the ecu must have used and absolute sensor reading 14.5 eng stopped but I soon realised it didn't change under load. The waste gate works as I have a manual boost gauge plumbed into the line to the boost sensor. So I have boost but the ecu reads none at all. I think there's an...
