samasaurasrex Posted December 30, 2016 Share Posted December 30, 2016 There been some strange rattling noises coming from my engine recently. Car sounds fine on idle but as soon as give it some revs it makes an awful rattling noise. Its been sitting in the garage for a couple of months now so I thought I'd give it a little spin and see if it still running ok (bad idea!) So the rattling noise was pretty much there all throughout the rev ranges, apart from idle and every now and then when I take my foot of the accelerator. I noticed it was getting a lot worse so I starting making my way home and thats when it got really fucking bad. The rattling just kept louder and louder until eventually it just pretty much died. I only drove about 2 miles with it making this awful rattling but it was rush our on the A34 so I didnt want to stop and fuck everyones day up lol. Also I dont know if its related but I've been having some issues with the battery recently. That was actually main reason for taking out today was to get the battery changed and its after that on the way home it started to get bad. It didnt happen everytime either but I also noticed that as the ratting got worse everytime I put the clutch in to change gear the engine turned off. I dont know if this is anything to do with new battery or the fucked engine though. There was also a fair amount of oil on the rocker cover around the breather. So now the car is back in the garage, I had to push it the last few hundred yards as it just completely died, its turning over now but just not starting at all. I dont want to keep trying to start it in case I cause any more damage. Any help would be greatly appreciated. I'll try and attach a video I took last month of the engine rattling noise to try and help.

Gainzy Posted December 30, 2016 Share Posted December 30, 2016 Do a compression test Quote Link to post Share on other sites
MR-2 Posted December 30, 2016 Share Posted December 30, 2016 Do a compression testThis. I have blown my pistons few times and all times engine were worked back to home easily, maybe little oil in windscreen, but it's only oil. Breather fumes act in good condition engine that way, that if You add more gas or rev engine a lot, You hardly see/smell/feel fumes, fumes comes only on idle. When pistons are gone, then when You raise revs, fumes comes very visible and oil fysically comes out from pipes and valves, maybe other seals too. Plus that ratling sound is there also naturally. Test Your engine this way, no need for compression test if pushing out out breathers when reving... Quote Link to post Share on other sites
MR-2 Posted December 30, 2016 Share Posted December 30, 2016 Here few of my GT pistons, engine still worked and rings were ok, parts dropped after taking pistons out of cylinder... Quote Link to post Share on other sites

Only a little bit of oil has out of the breather so I'm not too sure if it actually indicates anything. I'm gunna take it apart this weekend and see if can see what the issue is.

samasaurasrex Posted January 22, 2017 Author Share Posted January 22, 2017 Think I found the problem lol Quote Link to post Share on other sites
akyakapotter Posted January 22, 2017 Share Posted January 22, 2017 be fine on 3 cylinders lol time for a new lump cheers nick Quote Link to post Share on other sites
samasaurasrex Posted January 23, 2017 Author Share Posted January 23, 2017 Yeah I've started looking for a new one already. I'm not too sure where to go from here though, the way I see it is that I've got 3 options: 1. I could sell it as it is now and get fuck all for it. 2. I could buy another 2nd hand engine for a few hundred quid and hope it doesn't break on me too. 3. I could go all out and forge the fucker. Any thoughts?? Quote Link to post Share on other sites
jimmymac101 Posted January 23, 2017 Share Posted January 23, 2017 Option 3 is the only real choice there James Quote Link to post Share on other sites
4e_FTe Posted January 23, 2017 Share Posted January 23, 2017 Option 3 is the way forward 👍🏼 Quote Link to post Share on other sites
akyakapotter Posted January 23, 2017 Share Posted January 23, 2017 Option 3 if you can afford it Quote Link to post Share on other sites
redz11 Posted January 23, 2017 Share Posted January 23, 2017 option 3 for the long run imo, ive paid a lot in different engines over the years... worth the initial hit short term for reliability! Quote Link to post Share on other sites
samasaurasrex Posted January 23, 2017 Author Share Posted January 23, 2017 Still not sure what to do with it lol. Would love to forge it but it's a lot of money at the end of the day. I think I'll just keep it in the garage for a bit until I decided what to do with it. May be the perfect time to actually start a build thread lol Quote Link to post Share on other sites
redz11 Posted January 24, 2017 Share Posted January 24, 2017 saying that, the first time I did that to my engine, (cyl 2 and 3) they crumbled like the image above.. got new pistons for free (very lucky) swapped them over and all was good for about 8 months until I blew the HG lol..

samasaurasrex Posted January 24, 2017 Author Share Posted January 24, 2017 Unfortunately I think its done a bit too much damage to salvage the engine lol. Considering I drove about 3 miles back home on it with chunks of con rod flying around the engine haha Quote Link to post Share on other sites
Vturbo Posted January 24, 2017 Share Posted January 24, 2017 forge it, doesnt have to completely break the bank if you look around for parts etc Quote Link to post Share on other sites

jimmymac101 Posted January 30, 2017 Share Posted January 30, 2017 Both have there pros and cons mate you need to work out which company is better for your needs. I know a lad called kyle in bristol who has a MK2 GT and he sent his engine off to zisco or wepr and they forged his with great results James Quote Link to post Share on other sites
samasaurasrex Posted January 30, 2017 Author Share Posted January 30, 2017 Yeah true. I think that may be a bit out of my price range getting it shipped that far haha.. bet they did a cracking job though. Just out of interest, what do you think a fairly standard 98 V with a fucked engine is worth?? Quote Link to post Share on other sites
