Engine break-in: must do all at once or can do in separate sessions?

[echelon6]

Must I run all 6 to 8 tanks at once in an uninterrupted break-in process, or can I do things separately? e.g. heatcycle one night, then tanks 1-2 the 2nd night, and so on?

Take your time, not a problem.

That will be fine, you need to allow the engine to cool between tanks anyways.

Just curiously though wouldn't prolong breaks e.g. 24-48 hrs in between be totally different to the kinds of cool-down breaks envisaged by engine designers?

You want the motor to heat up (around 200F) and then cool down all the way, or at least most of the way. I would think that the bigger the temp changes, between it getting 'up to temp' and 'cooled down' would produce better results. JMO. So having your break-in span a few days may be a good thing.

It's all good to break it up. I've been breaking in a new engine for a week now.

 

[echelon6]

A week! wow you guys are serious

I have to break it up because I only have evenings to play with my toy, pretty busy these days.

Thanks for the info though, pretty satisfying to know I can do it over an extended time

 

[Lessen]

Well, it's only due to time constraints. If I had a day where I didn't have to worry about little ones or doing this or that I'd break it in in one day but it's tough for me to find that much time in one block.

My longest lasting engine was broken in over 2 days. (the 3rd TRX 3.3)
