Video for Triumph Rookies

[Tinster]

Here's a short video clip of a TR6
engine rocker assembly and push rods running
at 1500 rpms with the valve cover removed.

As quite the rookie myself, I find this little
clip really interesting to watch.

I hope the sound portion works.

enjoy

I guess you just had to see those valves in operation! It looked like all of them were moving. /bcforum/images/%%GRAEMLIN_URL%%/driving.gif

And yes, the sound was there. Did you get alot of oil spewing all over the place?? Didn't look like it was flying around too much. Maybe you're not getting enough oil up there...(that should start a bunch of questions and controversy)! /bcforum/images/%%GRAEMLIN_URL%%/devilgrin.gif

You just had to do that, didn't you Art???? /bcforum/images/%%GRAEMLIN_URL%%/pukeface.gif

Interesting... rotating pushrods.

I assume that the TR6 uses a flat tappet cam. The lifters on flat tappets are domed slightly, so as they slide across the cam, they rotate. I guess I never considered that it would also turn the pushrods.

Good way to tell which lifters are shot.

Dale you just love to see thing work huh?

Last year at Watkins Glen there was an old rececar there called a Franzese. it had a Curtiss Jenny engine with the exposed rockers that stuck out ot the hood. That was cool!!!
And it sounded like an old biplane too.

Not necessarily so. Years ago (80's), the aluminum block 4100 Caddy engine ate lifters and cams. Even with a dished out lifter the push rods would still turn from the vibrations and slight side to side movement of the lifter on the cam lobe.

Of course when it only lifted the rod about 1/8", you knew you had your suspect in custody.

Back then, no one would have believed that it would be the Northstar rocket that it is today.

Congrats Tinster,

I guess Amos is still running then ?

Now clean up the oily mess you made, put the valve cover back on and drive it!

Have you reached the big 500 yet?...I'm sure everyone at the forum has got their fingers crossed for you.

 

[tdskip]

Cool - I really enjoyed that. I'd never seen one of our motors in action like that.

Nah, he's getting plenty of oil. It only takes a little. Note how everything is nice and wet. The camera can't see all the little drops being flung from the valve end of the rockers (but I'll bet there are little specks all over somewhere). And note towards the end how there is oil being blown back up from the pushrod tubes, where it's trying to run into the crankcase.

Like so many other things, some oil is good, but more isn't better.

What a cool video! Enjoyed it, as Brian Williams says "thank you for that" heh.

Don't we ALL want to see whats inside the brains of our cars, don't we....If you look inside a GEARHEADS brain thats what you may find.Sometimes not ALL the valves are working.

You would be correct. So is the cam in your newly acquired TR3. If you haven't become aware of the ZDDP controversy for solid lifter engines (assuming your Camaro uses hydraulics, possibly roller)... You might want to search out ZDDP topics.

 

[Tinster]

Hey Ya'll !!

I'm really happy you enjoyed the video clip of the valves
popping up and down. I thought it was ever so cool to watch.

Yeah Bill- even as a kid I liked to take things apart to see
how they worked. Got many a "lickin" for dismantling stuff
around the house. The dismantle of my mom's new toaster got
me a particularly sore rear end. We won't discuss my dad's
HO train engine.

Now, I guess I'd better put Almost Amos back together
and get on with driving toward 500 miles.

later,

dale

The engine in the camaro is a SBC 400, with a Lunati flat tappet cam. I went with flat tappet because it was recommended by the engine build plan I was working from. Someone else did all the hard work of figuring out which cam was best and fastest. /bcforum/images/%%GRAEMLIN_URL%%/smile.gif

I've never seen it run without the valve covers on it. I adjusted the valves with the engine off.

I'll look into ZDDP.

Ah yes, I remember those days! I learned to find items being thrown away to take apart ... and even then I sometimes got in trouble for it. Eventually got pretty good at putting things back together as well, but always seemed to have a few parts left over ... Dad used to say I could take apart 5 lawnmowers and put together 6.

Hot Rod Magazine had a long article in the last two years about and may have kept up with new information. Its actually the lack of ZDDP in modern oils that you should be concerned about.

There are also a few threads here on the BCF that delve into it.
