Hi Graham

Curious what was used on your engine?

Hi Peter

I forget sometimes that other people have not had the misery of being trained in lubricant technology. By Zinc you mean ZDDP which is an agent that promotes oil film retention and metal to metal pre-lubrication. It has been reduced in some modern oils because it is hostile to catalytic convertors. It's advantage is at cold start and first start. But too much in a freshly built engine and you can face serious bedding in issues particularly the rings which need to wear into the bores to create a seal. This is why you start with good quality running in oil not the finest Synthetic you will switch to after running in.

If pre-lubes dry out from storage you get problems with blocked drillings and oil starvation issues. New cams MUST be given start up lube just before start up to protect the case hardening and they need to run at 2000 RPM for 5 to 10 minutes to bed in. With used cams I have used moly grease coating at first start up with no issues. I like the Kent Cam lube for new cams. It has all you need and is easy to get.

Some engines have designed in lubrication challenges so may need more start up lubricants. If you go this way the engines needs a regular turn over and warm dry storage just like with engine oil. But you also want to be doing a swap to fresh running in oil and new filter soon after the first run up to temperature holding 2000 RPM.

Ultimately you make your own scary decisions.

Thanks Eric,
I wasn’t aware the ZDDP content was being reduced in oils to save cat converters. I’ve always liked that feature of modern lubricants. Sad

Hi Peter,

I have to confess I am completely unaware of what was used on my engine build, but I'll ring Stanwood next week and find out what they use for engine reassembly lube.

Hi Peter,

Just rang Stanwood and they tell me that they use Lubriplate 105 as an assembly grease. Here's a link:

https://www.lubriplate.com/Products/Grease/Multi-Purpose-Greases/100-Series/NO-105/

They stock it and will be happy to sell you a tube. Guy was always effusive in his admiration for Stanwood, and I have found them beyond reproach in all my dealings with them.

Cheers,

Graham
