Burning oil question

[dblenk]

it seems my USA engine is burning oil (and a sump gasket leak)

if it goes down the valve guides on the head there is a seal kit that can be fitted, i am looking and thinking it cant be done with out the head off or am i wrong

compression is around 150psi on all cyls except No 1 which is around 120-130 (might have come up now i use the car)

over to you guys (or lads if your British haha)

Early discovery tdi or Ford cvh you can do it with the head in place but you need to check how far the guide protrudes and what springs are fitted 

[dblenk]

Thanks Marco i will check it out

Hi Neil trust all is good with you and the family i remember you saying about the discovery thats where i got the idea from

All good thanks and by the way  the seals have to be retained by the spring or you waste your time just saying.

browse the forum for „Elring“, the valve stem seals I used

Last years I have been told from friends driving behind me my TR is „a smoker“,

this year I asked the same friends and they stated this is not the case anymore.

Oil consumption reduced from 0.6 l/1,000 km down to about 0.3 l/ 1,000 km.

Could be different ons your TR.

A word of caution if I may.

I had the valve stem seals which are retained by the valve spring fitted. My cylinder head was stripped earlier this year and it was found that the seals had been destroyed. This is thought to have been caused by the high lift camshaft I had been running and possibly the valve guides sitting a little higher than they should. This camshaft had a .412" lift on the lobes, I've since changed to a milder camshaft and fitted new seals on the inlet valves only.

Hi Richard,

thank you for your worry, I checked the clearance to the valve collars and I had enough clearance when max compressed.

oil consumption from the top line on the dipstick to the bottom line over 200 miles but the lads behind say its only every now and then (hard acceleration)

i do have a sump gasket leak so maybe that doesnt help

i will be doing the sump gasket first then the cylinder head stuff

Triumph did not care too much about not to loose oil with the 4 cylinder engine construction.

The engine has multiple construction details responsible for loosing oil.

How does a cardboard look like laying under the car?

messy hahaha definitely need to get the sump sorted

[dblenk]

Talking to one of the lads fitting a ump gasket doesnt always stop leaks

what is the best gasket sealant, i have some blue stuff from Moss

(i am aware that bolts can strip the aluminium bridge, i will check it all before i fit the sump back)

i used hermatite red in the 80s ????

thanks in advance

Very often sump leaks happen because the flange has been distorted by overtightening the bolts, so the surface isn't flat. Gaskets can't seal properly if that is the case so before considering the goop you need to check the gap. 

If the mating surfaces are flat then a thin smear of Hylomar or similar on the gasket is all that is required, along with not over-tightening the bolts.

Ok Rob 16ftlbs i have a calibrated torque wrench was going to chexk the sump with a large striaght edge

if it is over torque they could have stripped the threads on the ally bridge also

[Lebro]

A cork sump gasket has a better chance of sealing than a paper one.

Bob

[Z320]

+1 for the cork sump gasket, bought NOS, but no longer produced?

This the paper gasket looks like when the bolts overtighted

The flange is punched by the bolts around the holes

I used this "tool" to bend it back, not a hammer, please!

Please notice, threads in the aluminum bridges go through in the engine and oil leaks out along the threads.

ooh yes a cork gasket

i will check the sump for straightness

will report back next week when hopefully i have time to remove it

thks

Use RTV both sides of the normal casket and around the the bolt holes

David,

To me, smoke on hard acceleration more is likely to be a ring, probably #1.  A cloud of smoke upon opening the throttle at the bottom of a long hill would, to me, point to valve guides.

If you drive gently, maybe an Italian tune-up might help free a sticking ring.

Peter

[dblenk]

A sticking ring ooh arr vicar

Seriously though yes i am nearly finished some of the bits and pieces and was going to get a professional tune there is a guy up here knows carbs very well i am more the injection stuff thks Peter
