white 2-70 engine

what is the average life of this engine? ours has a blown head gasket at 3200 hrs. runs well otherwise. time to rebuild to prevent major problems or is there a lot more life in this engine?

Diesel correct? Are you the 1st owner of this tractor? Sure those hrs. are correct? Does the tractor start good? Any blowby? Does it use oil as in do you have to add oil regularly? Motor oil analysis might tell you something too. Have you ever heard of an engine leak down test?

Others may weigh in here with more and better info and give you some advice on rebuilding the head.

If it was mine, I would pull the head and see exactly what you have. It ran good before, it should run good after a new gasket. Chris

First of all don't be just changing the headgasket. Find the cause of the failure. How does it start? I would check quite a few things before I made a decision either way.

owned tractor since new. no excessive oil use, starts good down to 25-30 degrees. have heard this engine spins bearings and throws rods at 3500-4000 hrs. don't know how reliable this information is. what is engine leak down test? i realize there is no crystal ball. thanks to all for your inputs.

You could bring the head into a machine shop and have it checked. It may need to be machined. If the head isn't true you'll just keep losing head gaskets. We (mainly my Dad and buddy) recently overhauled our 2-70 Diesel (Waukesha VRD283). Rebuilt head, new valves and resurfaced, ground crank and new bearings. Dad bought it as a mechanics special because the guy that just rebuilt the block (no head work) tore the o-rings on the sleeves thus allowing coolant to get into the oil. Thats why the crank was done. The sleaves, pistons, and rings were fine. Now its basically a fresh engine! Kind of a long post, mildly off topic, but oh well! I haven't seen it run in person yet, just YouTube. This weeked, hopefull, will be the first time!

Never heard of the 2-70 having any engine troubles. The 1855 is the one with a bad name. They did lots of updates to the engine during production and the later models as well as those that were updated will last a long time.

We've got a late model 1855 and it runs very strong with about 5000 hours on it.

If you have 5000hrs on a 1855, you might want to think about putting a new set of bearings in it. Old Ollie dealer told me that around 3500 to 4000hrs you need to change the bearings. Chris

before you do put it together for a hundred bucks the machine shop i used put steel o-rings in the head I don't remember the measurements but to explain it; they mill a 50 thou.deep groove in the head around where the fire ring contacts the head and they laid a 100 thou.wire in the groove this bites the gasket preventing compression blow outs i've done three this way and have not had any leaks. one is in a 310 waukesha putting out 310 horse at the flywheel it may be overkill but for the price it's cheap insurance

It was overhauled before we bought it- somewhere around 4,000 hours.

Been strong so far.

I just bought a 77 7-20 diesel 4wd. Being delivered. "starts rough" per auction/ runs etc. Do these have glow plugs? any other tips where can I learn more about it? thank you

Other than tinwork it's a late Oliver 1655. No glow plugs. Depending on hours it could be tired and need a rebuild. Otherwise it could be anything- intake, valve adjustment, or fueling, or everything combined.

Get that thing decked, in a excellent machine shop.

It does not have ‘glow plugs’ but has a manifold heater in the intake.
