Topic: 22RE break in questions

[Volcom]

What viscosity oil do you use to break a motor in?

What's the standard break in procedures? I've got a new cam. I've heard 2000 rpm for 20-25 minutes, run motor lightly, changing up the rpms for 100 miles. Change oil and continue to be easy on it for 1000 miles. Change oil again and you're set.

What viscosity oil do most 22RE Toyota guys running in CO use?

Do I need to spray oil into the cylinder walls manually before trying to start?

Thanks and sorry for the 100 questions, just trying to cover my bases before firing up my fresh rebuild.

I've always followed the same basic things for all my engines, 22r, hybrid 20/22, 3,4L, V8, etc...

1. No towing for 5000ish miles.
2. No high speeds, 55-60 should be ok
3. Vary the RPMs, don't take it easy, but don't be too rough. Give it some good revs occasionally.
4. Use good oil.

As for viscosity, I'm not sure what you guys typically use in CO, but 10W-30 or 20-50 should be ok, just don't want it to freeze up ..

Ha, I answered this on colorado4x4.com for you also so here is a copy of my response, pretty much what 4inchtoyotas said...

When I rebuilt mine I ran conventional valvoline 10W30 for the break-in process. Just run the idle up to 2000 rpms for the cam for about 20 minutes. change the oil, and check the valves again. Go easy for the first 1000 miles, but make sure you aren't going TOO easy, you can run the rpms up smoothly, you want to make sure it sees a good range of rpms during the break in, and absolutely no highway miles. you want your tach moving for those 1000 miles not stuck at a cruising speed. After the 1000 miles change the oil and switch to a synthetic oil. Hope this helps.

I use the RPM ranging method. Gotta have some time on your hands though but it works well.

Run the truck for around 30 min at 1500 rpm
Run the truck for around 30 min at 2500 rpm

go up in 1000 rpm increments until your running it around 4500 rpm for roughly 15 min's

This will give the engine that range of rpm's that it will probably see daily and will break everything in with increments.

Do you run with a load (driving down the road) or just revving the engine in the garage?

Thanks for everybody else's replies as well.  BDC, thanks for repling in two spots

I had a place called HT Machine build my hybrid for me. Tim from DOA recommended them. From my understanding he used to work with them before he moved east. Anyway, they've seemingly built quite a few hybrids, 22r's, et cetera, and they didn't seem to think a break in period was even necessary. Now don't get my wrong, I'm taking it easy for the first 1000 miles and then I'll change the oil and go at it, but when I told them that's what I was going to do they pretty much just smirked and said "If you'd like." Not sure how abnormal this sounds, just my experience.

no load, just sitting stationary.

has worked fine for years

Those are probably the same type of guys who start their truck and stick it in gear before oil even hits the top.  Any rebuilt engine needs a break in, period.  The only engine I wouldn't worry about breaking in would be one with a nikasil lining, but we aren't that lucky.  Even brand new sportbikes, with their super tight tolerances, are supposed to go through a 600 mile break in period.

I wouldn't rev it up over 3500rpm for atleast the first 1,000 miles or so, then change oil like you said.  I'd still take it easy for another couple thousand before chainging the oil again, but still wouldn't approach the redline.  You HAVE to seat the rings properly, and flogging it right off the bat will assure you don't seat them properly.

I have often wondered what the speed of a vehical has to do with engine break-in procedures.  The engine break in is effected by two things outside of the the actual engine parts, (1) Engine RPM, and (2) Engine Load.

It makes sense to not overload the engine with towing, but actual speed (mph) has nothing to do with it. 

As for being in Colorado, just make sure you are not breaking it in with cold starts!

[4inchToyotas]

Yeah, speed usually doesn't have anything to do with it, it just helps keep the engine load down if you're not needing to get it going to get to high speeds. I guess I was adding in some diff break-in too (at least how I do it).

Just make sure it's got some earl in it a go..shouldn't be that big of a deal. I've had mine out wheeling before the first 500 miles. I just need to tighten it all up and get rid of the oil leak
