Cheers guys, its going into Grant motorsport so he can have a look it. He will carry out a oil pressure test first and go from there, think thats my bet bet! Cheers.

Thanks sorry forgot to give info on the car, its a '93 k reg with 140k, limited history unfortunately and no records of the chains being done. Could it be the oil pump? thanks

Hey guys, I have searched through recent posts in the hope of gathering info regarding my problem. Whilst out driving on friday night and driving my VR like it was intended i realised there was a louder noise coming from the engine. Firstly before the new noise my chains were always slightly rattly and this never worried me! However whilst building up the revs suddenly it sounded like the chains were extremely loud. I limped the car over lifted the bonnet and it sounded almost as if the chains had become instantly louder. I had to start and move the car on the weekend and it starts and runs fine once the revs have settled (rattly when revs are high tho) and when i moved it around without touching the accelerator it was fine however once the revs reach 1000rpm or so the extrememly loud noise begins to come back. Im no mechanic however when i popped the bonnet and the revs were held at 2k it sounded as if the noise was coming from under the timing chain cover (or could this just be the top of the engine?? cams etc..?) Ive read posts and people have suggested oil pumps to fix a rattly noise and on the other hand Ive read post wher people describe that the chains are screwed when they start rattling at 1200rpm... Can anyone shed any light? Many thanks fred.

Cheers guys things are starting to becoming a little clearer. Will get the seal from vw. Am i correct in thinking that once the CP is removed the 3 bolts will be obvious and if so is the thermostat housing removed in one with the housing that holds the 3 temp senders? Many thanks again guys... Fred.

Oh if i remove the whole housing from the head do I have to change the seal thats in there? All I was given from GSF was a thermostat and a single o-ring so dont want to be removing things if when I fit them back together they'll start leaking! lol. Can anyone advise? Anyone got any piccys as to which bolts to remove to change the thermostat easiest? thanks again Fred.

Sorry just re-read your previous threads do you remove the thermostat housing from the block? i was trying to remove the bolts on the lower plastic underneath the thermostat. :?

Hi guys gone about replacing the thermostat. Have removed upper and lower rad coolant pipes to gain access however the bolts appear a pig to get at. I can see 2 and the 3rd is hiding somewhere. Are they 5mm allen bolts? If so what tool did you use to get in there? Am i doing something wrong? Many thanks Fred.

Hi guys, replacing the thermostat in my VR6 tomorrow anything I should be aware of? Is it straight forward? many thanks Fred

Asking on behalf of a mate who has a VR6 engine in his mk2 golf. He has purchased oil temp and pressure gauges and was wondering where they had to be wired up to? If anyone has any pictures that would be appreciated. Many thanks Fred.

Ok i will try spraying the coil pack later! Ive also been by a mate with a mk2 VR to remove leads from the coil pack end 1 by 1 to find out which cylinder isnt firing, he then suggested taking the lead of the cyclinder that isnt firing and swapping it with one that is! Is this safe and effective? thanks Fred

Ok cheers guys. Is it a possibility that water has affected the coilpack then? Just find it too co-incidental after a lot of water went over then engine. That test you carried out on the coilpack to check its effectiveness how do i do it? remove leads? Thanks

Nah it has a coilpack. Are these expensive? Is it possible that water may have leaked in there? How would you recommend removing water if its sat aound the spark plugs? Would it help removing ht leads indivdually from the coilpack end indivdually to isolate which cyclinder isn't firing and go from there? Cheers

Alright guys, another spot of trouble with the VR. Replaced the heater matrix on sat (in heavy rain) and the engine got extremely wet. Decided to flush coolant system whilst i was at it so a lot of water from that went over the engine too! I didnt think much of it until I drove it last nite, first couple of mins she drove fine but then occasionally started to misfire especially at low revs. Then after 5 mins or so was misfiring constantly and running on what sounds like 5 cyclinders. Drove 50 miles today and around 20 last nite and I hoped engine temperature would disperse any water that may be causing it to misfire but it hasn't, still misfiring. The car ran fine before the engine got soaked in water on sat prior to changing the matrix. Worring that I may have dropped a cyclinder checked the oil cap for mayo but its fine. Oil is clean and its not overheating. Can anyone suggest some tests to eliminate any possible problems. Cheers in advance Fred

Yeh Ive joined the club also! lol

Thats perfect! Thanks everso much I can go finish the nitemare job now! Fred.
