Bantam Noisy Lifters

Postby Eon » Mon Nov 16, 2015 11:02 am

So I have a reprofiled cam with shims in my Bantam. I had it installed while I was running the recommended Shell 15W40 oil, and I was experiencing noisy lifters on idle when the engine is up to temperature. New oil (Castrol Magnatec 10W40) seemed to sort the problem out but only for a few thousand kms.

Now it's almost time to service the bakkie again, but I'm looking for a superior oil that will sort out the lifter noise as it's getting so bad that the attendants at the petrol station are sending me to the diesel pump!

Sorry if I'm sparking an age old oil debate but if oil doesn't sort out the problem, I'm changing the cam back to the SWR1 billet.

You are using a good oil. Are those hydraulic lifters? Anyway, I doubt your problem is related to the oil, maybe pressure, but I would be surprised if Royal Purple or another Synth oil helps with that.

Yes, the Rocam uses hydraulic lifters. New oil solves the issue, but only up to a certain stage (initially noise only starts after hard driving, then a few 1000 km later it happens every time the engine gets up to temp) hence why I'm thinking it could be oil related. Maybe the oil gets too 'thin' when hot? It's almost silent when the engine is cold!

Maybe you are right, but this points to a wear/valve adjustment issue, as using EOM specified oil should not cause this. Hydraulic lifters do not like aggressive cams....They may be noisy on startup but once the oil pressure stabilises they should be quiet.

Received these today. Ordered them from greenmachine.co.za and received excellent service from Wilhelm!

Bakkie is going in for a service on Tuesday. Doing oil change first, see if it helps, if not I will gooi in the additive. If it's still noisy, I'm ordering a new set of lifters.

Yes, this is a problem that can definitely be solved with a decent oil. Getting the right viscosity grade is key here. Also your driving style will have an impact. Look for something with a good VI. The liqui-moly mentioned above is a good choice. From what i make out from the picture it seems to be a semi-synthetic containing, you guessed it, liquid-moly.

Someone mentioned Royal Purple above. Be sure to choose the XPR range if going this route. The other ones, the Royal Purple HPS, etc are not fully synthetic despite the claims and contain up to 50% of group 2 (hydrotreated) oil. Although Royal Purple is a very good product.
