850R Sticky tappet noise engine investigation
Ok, the MAJOR symptoms were suspected as being a very sticky tappet. Im in a bit of a hurry but basically I stripped the cam cover off and all looked ok, reported my feelings to a good mate who own DP Motorsport, conrod and another knowledgeable mate. they all said its a dead lifter. however, Im not convinced. Anyway, today will see me and Conrod put it back together, restart it and fingers crossed it'll be ok. Having said that, Im not convinced the tappet swap will sort it. Already seeing new rods, shells and bearings. (forged rods here we come).
I did a little 'BTCC 850' mod. Not because it adds any benefits but just 'coz I can. lol.
MY 'Lift'.....
V70R AWD, mint body, auto, Great runner and bog standard....for sale.
In for surgery
My engine as it is day to day.....
Slowly but surely.....
My little mod. lol.
Done. all done but lifters are not out. They are now tho. Going back together today with 20 replacement lifters. Fingers crossed!!!!

OK, spent the day today putting it back together with Mr Conrod. Mmmmmmmmm shiney!!! Clean as a new pin.
Close to done........
Restarted the car. Regular tap clonk tap clonk. Problem still there BUT not as bad a before, the top end is now super quiet. 'Seems we have a bottom end problem' says Conrod.
25 minutes later.....off comes the sump and the major culprit was........A spun main end shell in/on cylinder 3. Nasty.
NO major drama tho. Sump will be steam cleaned to be 100% theres no filings or general 'Clagg', pinch a good shell and end cap from 1 of 2 spare engines, carefully polish the crank (got a couple of micro scores), plonk in shells and end cap. refit sump. bingo.

Re: 850R Sticky tappet noise engine investigation
should be sorted and go for a restart on Wednesday mate. Steam cleaner isn't available until Tuesday night or it would be done tomorrow. Never mind.

Re: 850R Sticky tappet noise engine investigation
Tuesday evening scrubby scrub as planned. Spent 45 minutes soaking in degreaser, then, into the degreaser bath.....scrub scrub. Then attacked it with 1100 psi of 120C steam cleaner. High air pressure blow blow dry. Short of sandblasting it, It cant be any cleaner.....
Before......
After. Ready for re-install. More thanks to my good mate at DP Motorsport.

The V70R was clipped by some TW@T on Sunday night. destroyed the drivers door. Car is going to be written off say the insurers. My mate has now had the 3rd of the famous 'bad luck comes in 3's'.

Re: 850R Sticky tappet noise engine investigation
All went well on Wednesday. me and Conrod started at 9.30am. Spent a good hour and a half polishing the crank. Conrod whipped a shell and end cap from a low miles V70 T5 engine in my shop. Cleaned everything to look new. Reinstalled the shell.
In went 5.8 litres of new oil.....
Turn the key....nothing...battery discharged.
Conrod whipped his battery off then try again.....turn key...... bursts into life. Few strange noises then the car settled down....took it for a easy test drive and all felt great other than the engine felt very tight.
All done, conrod left and I drove home. Got home and no noises, car is now super quiet. My Mrs commented on how nice the engine sounds.
Went out to grab a pack of 10 ciggys late last night and can report the car feels good. the tight shell and gloopy new oil are freeing off. Still no nasty noises. Smooth as an Italian waiter.
Happy with it but for the next few hundred miles I will take it easy and bed the new bits in gently.
Happy to report I got away with it!!!!!!
