GU air box gasket

I was working under the bonnet of the GU on the weekend and I noticed a noise from the air box when I started the engine. After removing the lid of the air box I noticed that the gasket around the perimeter of the lid was totally perished and most of it was missing. I went to the local Nissan dealer to get a new one and he said it was not listed - I would have to buy a new lid. I did not even bother to ask for a price (he may have had to call an ambulance!) - and went straight to Rare Spares who had replacement rubber off the roll for $2.00 for a metre.

Good thing to check on your Patrol because if you have a snorkel and think you are safe to do a river crossing - the water will certainly get into the air box via the defective seal.

Its a cheap repair at $2.00.

interesting you should mention it. i noticed water in my airbox the other day after washing the engine bay. this seal appeared to be my issue to. how common is this????

Would be VERY common. The rubber ages over time, hardens/dries out and falls to bits. I suggest we all check our seals. Its easy to do. Just undo the clips holding the top on the air filter - undo the MAF sensor plug - loosen the clamp and remove the top - look under the lid and you will see the seal located in a square groove. If the seal is hard and brittle - it's knackered and needs to be replaced NOW. Simple and may save you an engine replacement.

Cheers Bill, rare spares, who would of thought of that. Nice work mate and thanks for the tip,

can't believe there isn't a Nissan spare for something in so many vehicles. GO NISSAN...

i raplaced mine a while back and got some from clark rubber make sure you do check it as i almost drowned my car because of it

After replacing mine, I did a seal test and found air still getting in somewhere. It took 6 months but I discovered air was still finding a way through the seal on the lid. I ended up using blue air sensor safe silicone and sealed it up that way.

Since then I've replaced the entire airbox with a high flow stainless steel unit from PatrolDocta. It has a simple rubber ring that does not leak, she also breathes a LOT better.

Looked at my airbox lid yesterday, same problem, gasket breaking up. So good tips on hoe to fix
