V6 Cologne engine sounds loud tappet rattles in my S2
Discussion
Just wondered if you got to the bottom of your noise?
I find mine is a bit noisy with the tappets set right. If i adjust the tappets a little tighter (say one or two thou') it will quieten a little but then definately lets by the valves, which is much worse an idea in terms of longevity and performance.
I think we are better off with a little tapping to avoid serious head-work.
Keen to hear if you found anything though

I know the 2.8 could have issues where it could spin a cam bearing in the block and cut off the oil supply to one of the heads - not a clue if the 2.9 can suffer this. I don't think its that common anyway but just check you are getting a top end oil supply before replacing anything. (Is the tappet rattle predominantly one side of the engine?)
Low oil pressure would also make it tappety if the engine is worn.

Well not much progress here, checked for exhaust manifold blow, can't find any problems. Also tried the old mechanic trick. Big screwdriver pointy bit against suspect parts and ear pressed to handle end. Sounds sweet as you like on the rocker covers, beginning to think the camshaft maybe the next suspect!
Brain fade,..... forgot to look for the engine number to see if I have hydraulic or adjustable tappets, watch this space!!

Before getting to pull everything apart, thought I would just go back to an earlier post and flush the oil system and use a non synthetic oil.
This seems to have quietened it down a little, maybe I am being picky and am looking for perfection and with an old V6 Ford engine this is gonna be asking a lot!

Gonna have a go this weekend and thought by adding to the thread it would then be easier to find all the good advice you guys offered.
Refurbing the rocker covers at the same time, and picking up the replacement seats, have re road taxed as well so those chilly morning runs are a must.
Busy TVR weekend.

Take the rocker assembly off complete and make sure all the oilways are clear. Pipe cleaners are good for this.
Not sure where the oil feed is on the v6 but on the v8 its a single 3 to 4 mm diameter feed to each cylinder head - it wouldn't take much crap in there to restrict or block it completely.

Ok so more confusing than ever now, conflicts with much of the good advice on here.
Engine number on mine
SA9DSN2****192** not the BR or B4 so not sierra or granada? Several numbers blotted for security.
An LL code, which according to Ford is 1990 manufacture which fits, and all points to the numbering means it is not hydraulic.
Which from all the info is the safest assumption. Set with the non hydraulic measurements as with the rocker covers off, there is play in most of the rockers not actually pushing a valve,,which would be wrong if it were hydraulic followers.
so going for it.

I may be talking to myself here, as its been so long getting round to doing the job.
The S is like a new car, no clatter, smooth roar, and you can hear the air being sucked into the injection system, just before the exhaust roars and the tyres squeal.
I had to go on a 50 mile road test to be sure.
Manual not hydraulic tappets, and they were a long way out of settings.
While the alternator was off, I refurbed the bracket, with a little high temp red paint, could be the start of a lot of tidying under the bonnet.
Very very happy, job done, not got any sense from engine numbers though.
