[Healeys] Fwd: Glycol in oil

Mon Feb 26 21:41:09 MST 2024

Bearing wear can also be caused by excessive oil pressure. 65psi sounds a little high. At some point it acts like a water jet…

Well, yeah – big-end bearing wear would do it, too!  Good luck on locating the source.

No, not a lot of oil is being pumped out of the rocker shaft.

I suspect bottom end wear.

Michael – is it possible you are losing oil pressure from the rocker shaft?

It is very easy to check – just warm up the car and then run it with the rocker cover off. The oil should seep out of the rockers, but a worn shaft will spray instead of seep.  I once had one that shot oil far enough up to hit the underside of the bonnet!

I agree with Bill.

I installed the DW steel gasket in about 2003 and 60K so or miles ago when I also put in upgraded internals and the DW alloy head, etc. I have not removed or retorqued the head since then.  In the last year or so a very slight coolant weepage (I can't even call it a leakage) developed on the right side of the head/block joint between cylinders 2 and 3 when starting from cold, which quickly disappeared on warm-up.

My main complaining symptom is a reduction in oil pressure both hot and cold from about 65/30 psi at warm revs and idle to no more than 40/15 psi commensurate. Though I renewed the oil pump and replaced the few bearings I could with the engine in situ a few years back this was of little effect.  I know there are those who say that oil pressure is overrated and our Healeys can live happily without it but I'm a bit on the compulsive side and can't keep my eyes on the road and off that needle, so off with her head, and more as over the winter the engine is being disassembled and line bored, the crank and internals crack-checked and refreshed as necessary, etc.

Though the DW steel gasket is supposedly reusable I am, with reckless abandon, going to install the unused spare steel head gasket which has lain under the boot Armacord in its original packaging for the last 20 years.  I feel the car has given me good and reliable service over these many miles and has earned the right to demand this splurge on my part.

I recommend the MLS gasket that Denis Welch supplies. It requires a very smooth finish, but if you can get that it provides a very good seal. I had the chronic problem of a leaky head gasket on my 100 And their gasket solved it.

Hi Roger, If your current fix fails, no need to despair.  After a 10 year chase to stop oil from getting into the coolant in my BN7 using multiple head gaskets and the Southern Carburetor drilling kit, etc., Hardblok

https://www.hardblok.com/

did the job perfectly. Attached is an image of where my builder put it, rolling the block to place the product where he deduced the seepage came through. In this specific use, I do not think there was much change in heat transfer. It worked for years, then I sold the car but suspect it is still doing the job. Jim Wojcik, MN

Up date.

So re-torqued head. Only one nut moved 3/4 turn. Added some of that Barrs leaks to coolant. Rigorous oil change (cooler too)

After 425 mi on new oil had another analysis done and pains still glycol present.

Now have head off.

Nothing really obvious.

Suggestions where/what to look for ?

Plan to take head to a machine shop for truing.

67 BJ8

Approx 15k mi on rebuilt engine by PO.

Recently detected water droplets and creamy oil residue inside valve cover and near oil filler.

Pains as engine and car run so well ... grr

Did compression test and all OK at around 150 psi

Also had oil analysis done that confirmed glycol in oil. Interesting no water found ... assume gets burnt off ?

Upon reflection realise had been losing some coolant. Have recently installed a recovery reservoir and attributed the loss to air being removed. Silly me.

So need some ideas how to proceed and if there is a likely culprit area  that others may have encountered ?

 Maybe start by re torqueing the head ?

Not sure how to retest though apart from another oil test.

Remove head ?

Thoughts and ideas please
