i just changed the rocker gear in the car and i noticed on number 1 exhaust valve stem was sitting flat with the retainer all the others are allright just wondering is this going to be a problem like the valve dropping ,and i have a small stutter from the engine when i just as i start to accelerate like its going to stall its not all the time.

I'd check it out or replace valve..The last thing you want to happen is rocker to hit retainer, keepers drop out then you'll drop a valve for sure!!!

I'm not a full bottle on this but I know the collets and valve have several grooves could it be that the collets are not sitting fully down or have moved up a groove , dont know how this would happen just a thought.

it all looks ok nothing broken its just sitting flat where all the others are up maybe 2-3mm .the ef rocker gear has stoped the noise and the retainer looks ok not cracked or anything .are valves expensive to buy i can put them in just thinking maybe change the rest and new seals

Its not so much the price of the valves, its all the work involved. Of course the head needs to be removed. Valves have to be synco-seated to the valve seats, best to change them, and the valve guides as well. All up it starts getting costly.

its the valve stem all the other stick out from the retainers about 2-3mm but exaust cylinder one the stem sits even with the retainer it dosnt stick out the 2-3mm like the others it looks like its been flattend and cant get pics its all back together .would it be cheaper to get another head rather than change valves ,the tappet on that valve was badly worn as well

Sounds to me like someone didn't put the collets in properly and like someone else said they are up a notch.

yeah id say th e one thats flat is teh one thats right
id also imagine cars not running that great caus valves wouldnt be opening as far as they could, your gonna need to take it back to where u had it done the valve springs should all look like this

that pic you put up rapier the rest look just like that all sitting at the same height but the first one on the left dont stick up above the spring it dont stick out at all i cant get a pic its all put back together it runs pretty good heaps power but when idleing it sounds lumpy but still smooth and it takes a while for the lifter to go quiet but it does go quiet and now i got a flat battery ,i left the lights on dammit

very strange i still think it be worth it ot have it check out the last thing you wont is a valve to drop down and hit a piston a new motor will be required then

it had a recoed head put on just before i bought it about 2 years ago so now just working out if its cheaper to replace the whole head or fix the valves, i would have to replace all the valves because i wouldnt trust the rest .but it does go bloody hard ,some freinds of mine have eb2 and ed and they reckon mine pulls heaps harder thans theres which makes me happy.
