Yep, I'm planning on installing the TR4A system with the gulp valve and 
vented valve cover cap.

I have done the opposite, removing the plug and installing a road draft
tube on my late TR4.

If anything what you have in mind should be even easier, but...

I installed the tube because the small opening on the TR4 valve cover could
simply not relieve enough crankcase pressure - oil was oozing from every
pore.   Perhaps the TR4A system is more effective though.

Geo, I'm wondering if your definition of "easier" is the same as mine! :)

It's my understanding that the early TR4s were identical to the TR3, i.e.
push-on valve cover breather and road draft tube.  The mid to late TR4s had
the air filters with the tube in the center with a flame trap coming from
the valve cover, no road draft tube and and the valve cover cap was a
sealed type.

The TR4As had a vented cap, gulp valve and no road draft tube.

I'm going to do some testing by installing the vented valve cover cap,
installing the gulp valve and I've temporary capped the end of the road
draft tube.  It will be a few days before I can test this setup as I'm
still waiting for the replacement gulp valve diaphragm to arrive.

Brad -

Just curious - what is your objective in trying this?

It may spare the environment some oil fumes as you drive and may or may not
decrease the oil drip on your garage floor (may even increase it depending
on engine condition).

I did what George did - reinstalled the tube and went back to the earlier
valve cover with the stack and filter cap.
Now I'm wondering about the Mishimoto oil catch system that Moss sells. Has
anyone installed this?

My objective is to track down and eliminate oil leaks.  I fix one oil leak
and another one or two show up.

I've had oil leaking from the timing chain cover center stud, the bolts
that mount the coil to the block were leaking, I always seem to have oil on
the heads of the oil pan bolts and there might be oil coming from the rear
main seal.  Also the timing cover seal was leaking as well.  The engine is
new with maybe 1500 miles on it and was built by a well known Triumph
engine builder.  The timing cover leak was fixed by adding a speedi-sleeve
to the crank pulley.

Unfortunately I've not been impressed at all with the engine builders
work.  When I first got the car (with new engine installed already) I
couldn't get it to stop smoking.  After multiple head gasket swaps thinking
it was coolant into the cylinders causing the smoking I finally realized
after the third head gasket that each time I pulled the head to replace the
gasket there was always about 4 tablespoons of oil sitting on top of each
piston.  I was so focused on coolant being the problem that I totally
missed what the oil on the pistons meant.

Looking closer I realized the cylinder walls were bright and shiny with no
cross hatching.  These were new 87mm liners and pistons that unfortunately
were never finished honed.  I pulled the pistons, cross hatched the
cylinder walls with a hone and that solved the smoking issue.  But the
engine has always leaked oil from seemingly everywhere.  However no oil
seems to flow out of the draft tube.  That may be a clue but I can't think
of what it might be.

The car came with a TriumphTune cast valve cover but didn't have a manifold
or carburetors.  So I installed a set of HS6s that were on the shelf.  I
initially tried the original style of air filters with the port in the
center and the flame trap.  The TriumphTune valve cover doesn't have a
baffle at the breather port and I ended up with an excessive amount of oil
going into the carburetors.
I then swapped air filters to the larger oval shaped filters and installed
one of Richard Good's PCV kits.  I still seemed to have some oil show up at
the carburetors so I have now installed an original chromed valve cover.
This seems to have slowed down the oil going to the carburetors but the
leaks elsewhere seemed to increase.

Since I have all the parts on hand to try the gulp valve and vented valve
cover cap I thought I would give that a try.  Yesterday I temporarily
capped off the road draft tube but I'm still waiting on a replacement
diaphragm for the gulp valve.  One of these days I'll do a leak down test
and a compression test but I don't think the rings are the problem.  When I
honed the cylinders I installed new Total Seal rings.

It may spare the environment some oil fumes as you drive and may or may not=
 decrease the oil drip on your garage floor (may even increase it depending=
 on engine condition).

It's my understanding that the early TR4s were identical to the TR3, i.e. p=
ush-on valve cover breather and road draft tube.  The mid to late TR4s had =
the air filters with the tube in the center with a flame trap coming from t=
he valve cover, no road draft tube and and the valve cover cap was a sealed=
 type.  

I'm going to do some testing by installing the vented valve cover cap, inst=
alling the gulp valve and I've temporary capped the end of the road draft t=
ube.  It will be a few days before I can test this setup as I'm still waiti=
ng for the replacement gulp valve diaphragm to arrive.

Brad

I have done the opposite, removing the plug and installing a road draft tub=
e on my late TR4.

I installed the tube because the small opening on the TR4 valve cover could=
 simply not relieve enough crankcase pressure - oil was oozing from every p=
ore.   Perhaps the TR4A system is more effective though.

Geo

I'm contemplating removing the road draft tube on my TR4 and am wondering i=
f anyone has successfully removed the tube and installed the plug with the =
engine still in the car.  

Thanks!

Johnnie, I have tried using the modern PCV valves which is what is
currently installed.  I purchased the PCV kit from Richard Good due to
reviews I had read online.  The only difference between my TR4 PCV setup
and the one in your picture is my TR4 has had the brakes converted to TR6
vacuum boost brakes so I have a Tee in the line between the PCV valve and
the intake manifold that goes to the brake booster.

Do you still have the road draft tube or is the tube opening plugged?

Also, is your valve cover cap vented (i.e. TR4A style) or non-vented?

Those terms (or something) confuse me.

My late TR4 does not have a vented cap - it seals tight.  I presume that
TR4As are similar.  Early TR4s and all TR3s had a cap that vents to the
atmosphere.

If you are fighting blow-by (and I think you are) it would seem that a
vented cap might help -- and since your engine apparently has a road draft
tube fitted as original then I believe a vented cap would have also been on
it.

Well, I bought the vented cap when I bought the valve cover from TSI. It ha=
s a hole on the top, but who knows how much it's really venting.  I have ro=
ller rockers installed so I need the extra room.

No, the draft hole is still plugged.

A mechanic once told me that is you take the valve cover cap off when runni=
ng, then put a shop rag over it you should only see a little deflection. Wh=
en I did it to my car it went up 3-4 inches. That was my big clue that I ne=
eded more venting.

All PVC valves are different and each handles different volumes. Some have =
springs that only actuate with a pressure differential. I don=E2=80=99t kno=
w about the GP PVC valve but you might look around for another. They're che=

>From all of the documentation that I've been able to read there seems to be
three variations of the emissions equipment.  The earliest is like the
TR3/early TR4 with a vented breather cap and road draft tube.  Then at
engine number CT14234E through end of TR4 production the cars had air
filters with vent openings coming from a flame trap from the valve cover
along with a "sealed" valve cover cap and no road draft tube.  TR4As had a
gulp valve with a vented (1/8" metered opening in the cap) valve cover cap
and no road draft tube.  This information was found in Service Bulletin
T-65-25

Your TR4 sounds correct having a sealed cap.  The TR4A valve cover caps
were definitely vented.  The TR4A caps have a nice little vent mechanism
attached to the top of the cap.  I'm not convinced that I have blow by.  I
will do a leak down test to verify but I won't have time to do that for a
week or two.

My particular engine is original block for the car but has been rebuilt.  I
don't think it should have had a road draft tube because it's well past the
CT14234E number.  It should have had the closed circuit system like yours
originally had.

I've attached the service bulletin but I don't know if PDF attachments are
allowed.

My guess is the vented valve cover cap on the aluminum valve covers isn't
vented very well.  Triumph spec'd a 1/8' metered valve in their vented
filler caps.

That's a great tip on how to check for excess pressure in the crankcase.
I'll have to give it a try next time I have get the car out.

I think I've tried 3 different PCV valves and since I have the parts will
try the gulp valve.  Should be a interesting experiment!

Thanks for the info.

Brad
