Hi Guys,
I have some oil leaks on my 86 6.9 and would like, if at all possible, to get a couple of years out of the engine before having to replace both crankshaft seals.
The engine seals are original and have only started to leak noticeably, a few months ago (six or seven months before storage). The engine runs clear and there is no blow bye from the oil fill neck - with cap off. Incidently the truck has been stored in a shed for almost a year, but now I want to get it ready for the coming winter. My guess is about 2 litres oil loss over 5,000 km.
It is a long shot, but I was wondering if there is an additive that is added to engine oil, to cause shaft seals to swell slightly ? If there are, are they any good and what brands would you recommend. I know that some people swear by these for auto transmissions, but never having had a serious transmission leak, I don't know. Of course there are a lot of people who profess to have had success, but I would rather hear from you guys on this forum.
So, in short, is there any additive that can be used to help seal crankshaft oil leaks ?
Oh, and yes I do intend toeventually replace the seals, but at the moment I am pushed for cash etc.
Thanks in advance for any infomation you could provide.
