Why the rebuilds?
I do not know the real long term effects of ULSD. My local CAT dealer says
that there should be no problem if the engine is in good shape. I'm waiting to see. I remember all the talk of failure when the unleaded fuels were introduced in the 1970s. I was running a 66 ford pickup pretty hard pulling a 4 horse trailer between Tehachapi and Santa Anita and was concerned. That truck finally broke a timing chain in 1989 with 346,000+ miles on it. It went the last 266,000 miles on unleaded. I have 200,000+ miles on this 3208 and it is using some oil so a rebuild in probably in the future with or without ULSD. The last 33,000 miles have been with ULSD and so far so good. Time will tell.... - Chuck Wheeler- FC 31SB Fort Worth TX _____ From: WanderlodgeForum@yahoogroups.com [mailto:WanderlodgeForum@yahoogroups.com] On Behalf Of bubblerboy64 Sent: Tuesday, September 04, 2007 5:41 PM To: WanderlodgeForum@yahoogroups.com Subject: [WanderlodgeForum] Re: Why the rebuilds? Very good point Chuck. That perhaps explains at least partly why diesels work well in the vehicles in which they work well. Over the road trucks and buses and taxi cabs to mention a few. I have heard some mention that there are down sides to the low sulpher fuels. Perhaps you or others might speak to that subject. I really don't know a thing about diesel fuel. Might be time to learn a bit on that subject since the credit card shows I am buying my share. Aw the ole first of the month bills.

Why the rebuilds?
Chuck: The ULSD definitely increases wear. My last oil test revealed
an increase wear with tin. I was not running a treatment at the time. I am now using a good fuel treatment and hope that solves the problem. It might based upon information from my filter company experts. R.E.

Why the rebuilds?
Tin is in the bearings, iron is in the sleves and valves. If excess
iron or alumnium, I would look at the fuel ????? Did they say how the fuels could fill your test with tin? I would send in the oil filter if you have concern. the larger particles dont show up in oilsample tests. I dont do oil sampling because the news is never good. Its like looking out at the street to see if your car is stolen yet.

Why the rebuilds?
-------------- Original message --------------
From: "Gregory OConnor" Tin is in the bearings, iron is in the sleves and valves. If excess iron or alumnium, I would look at the fuel ????? Did they say how the fuels could fill your test with tin? I would send in the oil filter if you have concern. the larger particles dont show up in oilsample tests. I dont do oil sampling because the news is never good.

Pete, with oilsampling, you and Ron are surly in a more informative
position then I. The problem with the information is Trends prove need for major service or repair that add too much pressure for $ action or caution for use. Newer Cat products have identifiers in various bearings that allow oil contents to define what bearing is wearing out. Without that pinpoint of issue, the information more or less says "UTT OH, time to replace everything" Antifreeze in the oil is an informative find but the chance that you will find that the headgasket just started to leak prior to your 10,000 mile oilchange is slim. They say the first signs of aging is grey hair. Bald, I never acted to correct the issue until I was old enough to realize any vain attemt would be invain.

Why the rebuilds?
A 3208 should go about 250,000 miles before overhaul, I have seen some go as
high as 500,000 miles.. Because it is a parent block engine ( no liners) The block usually is oversized to 10, 20, 50 thousands and this requires new pistons and rings. Like howard said the early guys had a lot of problems, NO 1 of all times was the valve springs, they would break. Cat replaced every set in a 3208 in a on highway application. Number 7 and 8 pistons would gald due to over heating. bigger theromstats solved this. Early models have low compresson on one bank causing a lot of white smoke at start up. If it is turbo or turbo and after cooled all these problems were solved before production. I think now it is a good sound engine use a good grade 15-40 oil. You can also buy a remaned short block or long block from cat as a repair option, Don't buy one with a crankshaft turned 50 thousandth. > From: "Howard O.

Hi Folks,
R.E. Brake aka The Putney Flash was service manager for the Cat dealer in Albany, Ga. He is now a Cat special project manager for the military. He knows a lot of what he speaks. FWIW. Howard T., [Non-text portions of this message have been removed] |
