Timing belt a tooth out on cam sprockets?
JerryS replied to soldave's topic in Engine & Ancilliaries/Gearbox
Hi Dave, just wondered - the marks may look aligned but are they level with the sprocket centers? -
Just saw this: https://www.ebay.co.uk/itm/Lotus-eclat-S1-521-W-reg-for-spares-or-restoration-engine-runs-COLLECTION-ONLY/202350913968?hash=item2f1d0de9b0:g:wvUAAOSwdIVeZ7dm

I saw this mentioned over on LotusTalk. https://www.ebay.co.uk/itm/1977-Lotus-Esprit-S1-/264673233906?hash=item3d9fc10bf2%3Ag%3AM7QAAOSwLfNec-jL&LH_ItemCondition=3000|1000|2500&nma=true&si=Y1qRzclelgy%2FmR8FrVW06RAD61U%3D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557

Been looking forward to seeing that. Some great behind the scenes footage.

Thanks for that description. Wasn’t pictured but that advert said they supply a special extra long tap, your work around sounded good. The last helicoil I did was on a couple of exhaust stud threads. I was hoping to fit longer helicoils than the ones supplied but found the tap couldn’t cut deep enough to the bottom of the hole. I guess at least the head studs have a better chance with the reduced nose where they bottom out. I have a block which had suffered from the head studs corroding in. Got them all out in the end but I'm going to have to revisit the situation. Re gasket/head stud issues - I’d noticed the Northstar engines having similar problems and this radical fix using studs with unequal ends. Not sure if this could be possible with the 9xx block though. https://www.youtube.com/watch?v=wqEj9BKlVEE

Hi Thomas, did you repair this successfully? Just asking as I wondered how feasible it is to repair damaged head stud threads recessed so far down in the block. I recently noticed this insert kit on ebay (in the US). https://www.ebay.co.uk/itm/LOTUS-ESPRIT-907-910-912-ENGINE-M12X1-75-CYLINDER-HEAD-BOLT-STUD-THREAD-REPAIR/153450133860 - Jeremy

Cambelt adjustment..how often after replacement?
JerryS replied to DaveyT's topic in Engine/Ancilliaries
Dave I noticed this post on the Lotustalk forum from Tim Engel re crank position for frequency test... https://www.lotustalk.com/threads/timing-belt-tensioning-with-a-snark.470848/#post-5965838 -
Yes SJs and also just seen PNM have the belts listed...

Do they have to come out Tom? Be good to use new ones in your replacement block. - Jeremy
