Triumph TR6 - Rocker oil feed kit???
I have a question for you guys. Back in Dec. and April of 2003 there were a couple of threads about rocker oil feed kits but they seemed very inconclusive, some yes some no. My 6 had one when I bought it but after rebuilding the head I found the previous owner had over tightened the banjo fitting and it snapped of as I was reinstalling it on the head. The question is should I bother finding a new fitting, or dump it. After four years anyone have any new opinions???
I have the rocker oil feed line on my engine.
Does it help? I do not know. There are engine techies here that say it does nothing. I suppose if yours is broken, do not bother fixing it.
I will say that mine does not have one. BUT and a big BUT... when I rebuilt my engine in 2004 I had to replace the rocker arm due to more wear of the arm at the front end of the engine (opposite to the oil supply end). This may be related to lack of lubrication to that end and may be alleviated by the extra feed line.
I am not exactly sure how many miles were on the engine when I rebuilt it but I would guess upwards of 40,000. I do not know how well the car was cared for for that full 40000 so I don't know if that had an effect either.
Due to the uncertainty of the effectiveness of the feed kit (as posted on this BBS) and the reasonable cost of a new rocker arm and the ease of replacement, I felt it wasn't worth the expenditure at the time (it was a low priority expenditure)
I have put about 4000 miles on the car since the rebuild and I have not inspected the arm yet. I probably will at 6000 miles. (this winter)
The problem with the rocker oil feed line is that the only thing it accomplishes is to put MORE oil at the back end of the rocker arm. Not saying this is bad but still a lack of oil at the front.
|Well no one has any thing convincing to say one way or the other, I think Iíll pull it off. Iíve got good oil pressure and a newly rebuilt shaft and rockers, if they go bad Iíll have an excuse to by more expensive roller rockers.|
|IF YOU'VE GOT GOOD OIL PRESSURE, DON'T BOTHER. BUT, IF AN ENGINE IS WORNED, ANY OIL GOING TO THE HEAD IS A BLESSING. IT'S NOT A BAD THING TO HAVE MORE OIL GOING TO THE VALVE TRAIN. |
AFTER MY REBUILD, I DECIDED TO TAKE MINE OFF BECAUSE THE HOLE IN MY VALVE COVER CAP WAS BLOWING OIL ALL OVER MY ENGINE COMPARTMENT.
I bought the kit but have not yet installed it. All I can offer here is that Richard Good of Goodparts strongly recommends the kit when using one of his GP2 or GP3 cams. Since I have the GP2 I will be using the kit.
|Hi Curt |
When you get the roller rockers, put it back on. I have Goodparts RR's and the external feed with a competition oil pump. There is a lot of oil at the top end it keeps me happy.
As long as it is in the right places, you can't have too much!
|One of the big problems with the oil line is the extra oil in the valve train and the possibility of losing that oil if you run a after market cover. Seems most people have been removing them unless you do the cover fix. See valve cover post.|
|Damn, hit the wrong button.|
Here is a photo of the intake on a 6 that had the unbafflr=ed cover with the aux. oil line.
|Don - it's interesting that the oil seems to have affected the exhaust ports only. Are you saying that with the rocker feed, the valve cover gasket is more likely to leak and the gasket is evidence of this??|
|Roger, it seems to cause excess pressure and if you don't have that baffle it will blow right into the hose and drain into the carbs and then OUT the exhaust ports. Some where noticing a large consumption of oil.|
|Hey Don, that sure is a shiney manifold you have there . . . can I ship my spare to you to work your magic with a buffing wheel and rouge?|
|Don - gotcha.....and that's exactly why I had to put an oil catch tank in - it was stuffing up the mixture..|
|I wish that was mine. actually it is an owner in the NE who took his manifold off to change to a trip set up. And that is what he discovered. |
I do have a ceramic coated shinny early style manifold up in my storage area. i use a late model black ceramic coated one.
|Just a quick note regarding baffles and roller rockers, while I like Charlie's baffle on the other thread, I don't think it will work with roller rockers. They are much bulkier than the stock ones and require a much smaller baffle.|
Here is what we did on mine. It is a piece of thin (.020") 5052-O aluminum sheet stock that was formed and trimmed to fit. The baffle was clamped to the cover at its mount location and two holes were match drilled through the cover and the baffle. It was then bonded to the inside of an extremely clean cover with hight temperature epoxy. Finally two solid rivets were wet installed with the same epoxy and bucked to form the inner head. It has been a while since this was done, and i cannot remeber which rivet diameter was used it was either a 1/8" or a 5/32" diameter.
I dare say that you could probably use a blind rivet as long as you made sure to wet install with epoxy AND filled the "nail hole" in the rivet with epoxy.
