Best Engine assembly Lube?

Question

Which is the best Engine assembly Lube? or Do you think “best is to mix some grease with engine oil”?what is your take on this?

Robert Mills:

Suzuki recommend moly paste as it stays where you put it. I was told to use it when i did my apprenticeship and am still using it nearly 30 years later. you only need a dab as the oil washes it away when you start the motor.

  1. I always just drench components in engine oil except for the oil pump I fill that with Vaseline. Gives good suck from the word go!

  2. Assemble it with the oil you are going to use . Fill the oil pump with it and soak the filter

  3. why do some engine builder use it a lot? I am using same regular engine oil which i fill it before starting the engine.

  4. You shouldn’t use grease it keeps the oil off the components leading to premature failure. I’m not talking from experience 3 rebuilds later wondering why I was only getting 500 miles before the engine failed again!

  5. Where I work, building engines, at around 1m year, we use a lube called P70. It’s a fine watery lube that looks like calomine lotion.

  6. I use Moly Grease mixed with oil never had a problem on my triumph bonneville.

  7. You can use professional assembly lube, the brush on stuff like what factories use…but why, when just plain old engine oil will do.\nI’ve only used pro stuff when I knew the assembled engine would be sitting on the bench for 6 months, as oil would just travel down with gravity, the brush on stuff stays there.

  8. Depends… if you are building an engine that wont be used for a long time, then an engine building paste is OK to use. I used to use the Red Line Assembly Lube. Most of the time though I just use engine oil. I always fill the oil filter if I can, and leave filling the engine with oil just before I am about to start it, especially with OHC cam engines. This ensures the cam and followers get a good start in life! If I can I also spin the engine over with the plugs out to build up a bit of oil pressure first if I can.

  9. When I did a course at Honda we rebuilt an engine using graphite grease

  10. Tony Lloyds advice is the same as mine

  11. Red Line assembly lube Oil is ok, but I personally use assembly lube.

  12. Engine oil but I usually use 20/50 on shells and shafts

  13. Suzuki recommend moly paste as it stays where you put it. I was told to use it when i did my apprenticeship and am still using it nearly 30 years later. you only need a dab as the oil washes it away when you start the motor.

  14. Wynns engine building paste.\nGot a stash from a mate who used to have a reconditioning business before he retired. Don’t know if it’s still for sale. But I have enough to last me so that’s what I’ll use.

  15. Grease will stay sticky and block oilways use the right stuff to start with… assembly lube

  16. Use the same oil that will go in the engine when its running numb nut

  17. Oil is ok when the engine is fully lubed and running, but starting from rebuild requires persistent protection for bearing surfaces until the oil system is fully primed and effective……….numb nut ­čÖé

  18. What do you wax your willow with old boy

  19. Linseed oil of course

  20. Permatex ultra slick engine assembly lube

  21. Ok guys now if I say we dont get anything above in my country then whats the alternative for that. So oil is the only option? Importing is big time costly….

  22. When I was a lad we only used engine oil, no fancy paste or shit like that, never had a problem.

  23. Oil mixed with CV grease.

  24. Stp. or or assembly paste from engineering shop

  25. Assembly lubs, especially on cams and followers

  26. 2 stroke Caster oil in bottom and top end and 10w40 in gear box \nIv also always been told it better to use too much rather than too little

  27. 10/40 engine oil. Been building bikes for 35 yrs. Copper slip on bolt threats. Moly paste on cam lobes and bearing shells.

  28. Wynns oil treatment for me if the motor is going to be left for a while. Seems to stay stuck to where I put it.
