im pretty sure its water proof. if it were me i would do both sides of bulk head a good few layers under tunnel

that should still help! most of the noise does come through the floor!! ive got a noise killer engine blanket on mine. doesn't make much difference but i suppose it all helps!!

just looking at the 4mm stuff. i think you would be cheaper doing what i did. cover everywhere in 2mm. then on the big areas add extra layer of 2mm in centers of big panels. it will cost a fortune doing everything in 4mm. and i think there is only 24 sheets in the 4mm bulk pack so will only...

check your leak off pipes for......leaks:) when they perish and they do, they let air in so needs to crank a few times to get the fuel back in the injectors

here is a little unscientific test i did with silent coat, mass loaded vinyl and rubber mats https://www.youtube.com/watch?v=kjixeCkSxB4&list=UUf_5uG8etFh7eThbmvanACA

ive started with silent coat. bought a 2mm bulk pack and used it at 100% coverage over seat box, footwells, tunnel etc and what i had left after all of front, i had enough to 100% cover one rearwheel box and half of the other!! i was only gonna use it over 50% to go twice as far but once all...

right after a lot of removing filters taking pipes of etc etc im starting to think im just being paranoid about induction noise!. Im convinced my exhaust internals are knackered as it has a very deep boom and whilst sticking a brick on accelerator (in neutral of course) i spent ages walking...

the full of soot thing is interesting, as been running with dodgy stem seals for ages and it kicked out a lot of smoke! also when recently changing head the exhaust ports were caked in oil!!

yea its a van back. something is not right then, when i say mine booms it REALLY booms, at 55mph cant here engine at all, or wind noise!! or stereo! its really loud! its definitely not blowing either been right round it !

right, been having probs with booming 110 300tdi. gonna try changing some exhaust parts to quieten it down as at 50mph its over powering!!! currently has a solid decat- OME center silencer- unknown make rear silencer. at tick over it sounds nice, veeeeery deep bass sound. now after a bit of...

no haven't checked for splits. will do tomorrow! other possible causes now? 1.dodgy air filter, will remove and drive tomorrow. 2 de laminating turbo hose??? would that make noise under load? what about a valve not opening enough? slightly bent push rod, worn tappet guide or followers or...

this is doing my head in now! pardon the pun!!! right after fitting new amc head popping has gone engine runs quieter and seems good. BUT i still have this booming noise from induction side!!! when i put my ear to air intake and rev it sounds like a sports exhaust!!!!

new AMC head fitted, popping gone! result

just putting this thread to bed. new turner AMC head, SORTED!!!

decided not to risk it and broke out the credit card! brand new turners AMC head built up 435+vat!

im not convinced its a fueling prob! it was fine until i put unknown head on! anyhoo ive got the unknown head off again and cylinders full of oil!! ALL the stem seals were pushed to top of spring !! so zero sealing at all!! i know this wouldnt cause a cylinder not to fire but im guessing the...

hmm i would have thought gas could pass through if oil can. was just a thought. cheers

done, still in same cylinder so im guessing low comp in no3

does this sound feasible? whilst inspecting the original head (now off car) i discovered ALL 4 exhaust valve seals were sat at top of spring!! so effectively no seal at all. i understand oil will be getting into bores, but surely as the exhaust valve opens and the spent oxygen is forced out...

so chances are they are new heads. cheers!
