jase4072 Posted January 31, 2021 Share Posted January 31, 2021 Hi, I've had my Z for just over 8 years now and its just started knocking!! :( It's a sad Z day. I've kept the oil at the top mark since having the car changed the oil and filter, checked the tightness of spark plugs but it's still knocking. Any advice will be greatly appreciated. Thank you. https://www.youtube.com/watch?v=_khbXaHwcr4&feature=youtu.be Quote Link to comment Share on other sites More sharing options...

ZMANALEX Posted January 31, 2021 Share Posted January 31, 2021 Sorry to hear of your engine woes. It sounds like bottom end to me, however, difficult to be informed from where I am sitting. I would firstly get a stethoscope on it, to trace the area of the noise. Another thing to check is that the main timing chain tensioner is not broken as these are weak and prone to breaking, however this would give you a heavy ticking noise as would a lobe off one of the cam shafts, so the noise is pointing to bottom end, crank, con rod area. If that turns out to be the case and you require a known, preowned, low mileage, Rev Up engine, then just give me a shout as I am removing one from a car this week. Alex.

jase4072 Posted January 31, 2021 Author Share Posted January 31, 2021 Thanks Alex, I've had the screw driver to the ear and it sounds quite loud at the front top front right of the engine so that could be a tensioner issue. However, when I got under the car it sounded loud there too but couldn't pick up anything with the screw driver trick. I have an 07 rev up engine, I'll take it to the garage and see if they can better locate the sound but may have to consider the replacement option. I'll PM you reference that if that's Ok. Thank you.

Willsy1980 Posted February 1, 2021 Share Posted February 1, 2021 Yeah sounds very much like a rod knock that one, for the cost of some oil probably worth draining it and checking for shiny and or magnetic bits. Quote Link to comment Share on other sites More sharing options...
jase4072 Posted February 1, 2021 Author Share Posted February 1, 2021 Alex said the same, I'm swapping out the engine, it's the best option in the long term What I will do is strip the old engine down to see what was wrong and build up some VQ experience at the same time. At least that way when I'm left with a box of bits it won't matter!! Thanks for replying. 1 Quote Link to comment Share on other sites More sharing options...
