Cyril Gibb Posted June 29, 2015 Report Posted June 29, 2015 I have always preheated before starting when it's below 45F or so. I understand the issue of pistons expanding faster than the cast cylinders with the potential to have 0 clearance. A theoretical question: What if the engine was started for just 30-40 seconds, enough to get oil splashed up to the cam and then shut it off for a few minutes to equalize the temps and then repeat a few times until temps were all sufficient to keep it running. Comments?
Hank Posted June 29, 2015 Report Posted June 29, 2015 The wear all happens at the beginning, while the starter is pushing the pistons up and down with little lubricant due to its increased viscosity. It is also a good reason to not start with a lot of throttle and get a large initial RPM surge [although I know people who do so routinely].
yvesg Posted June 29, 2015 Report Posted June 29, 2015 Cyril, you are giving me the chills here... isn't it the summer in TO too? Yves

Yep and don't forget to bring along your fishing net. Not to land that beautiful trout, rather to snag those foot long mosquitoes that have been know to suck a small pet or baby dry. And that are better controlled with a 12 gauge shotgun instead of a can of Off. Sent from my iPad using Tapatalk

Comments? I would think running a preheater would be cheaper than a new starter.....
