Can heavier oil help rod knock?

If it’s detonation (often called knocking or pinging), different oil won’t help. If it’s rod knock, the bearings are gone. Using much thicker oil should give a bit more oil pressure, and might reduce the knocking a bit, but the only fix is to rebuild/replace the engine.

Is engine knock dangerous?

Although detonation is the most harmful kind of abnormal combustion, you need to diagnose and correct the fault causing other mild forms of abnormal combustion as well since they can develop into detonation. In fact, any form of knocking left unattended over a long period can seriously damage the engine.

Can low oil cause rod knock?

Engine rod bearing and main bearing failure usually occurs due to a lack of lubrication (caused by a low oil level or infrequent vehicle maintenance). When the bearings fail, they create an excessive amount of clearance between the internal engine components, leading to a knocking noise.

Can I drive with a rod knock?

yes, you can do it. put some heavyweight gear oil in the crankcase, if one cylinder is knocking, pull the plug on it to diminish the pressure on the rod and lessen the knock, shift at 1500 rpm, keep your revs low, drive slow, coast as much as possible.
