I have gotten old and lazy Sold the RTO6610 eaton out of my 75 Ford and putting in a 1000 allison out of a 06 chevy.While everything is apart desided to see why the motor had soo much blowby had it for along time.A few guy's kept saying it was a head gasket.Time to pull it all down and find out.

Got the motor out and toredown fornd the #5 piston had the top and 2nd rings broke.There was all my blowby.I orderd rod and main bearing from Perkins.They wanted way tomuch for the rings.I called Hasting told the tec.lady all the ring messurments she told me that they don't have keystone rings that I would have to michine the top grove out for staight cut ring and put 2compresson rings on the top one.$214.00 and 2days I had the rings in hand.It took 6weeks to get the parts from Perkins and the stock rings were 4X of was hastings cost.I turn up a Mack for the guy that did the ring croves for me.

Took the head to the machine shop and Jay shimmed the valve springs from 45lb to 70lb they were a little light for a exhaust brake.evry thing looked good untill he put a vacum test on the valves exhaust did good but some of the intake weren't sealing.found out that 1/3 of the seat was ground wrong.Then he did a valve job before I was aloud to take it home monday I walked in the door at 1:30am Jay stayed late because he didn't want me to have to drive all the way back again.While it was apart I cleaned up the ports alittle.They didn't need alot as you can see.Intake valve is 1.74 don't remember what the exhaust is.Port matched the intake and exhaust manifolds to.

looks awesome..how are you doing the trans wiring?..i've been thinking of doing a allison 1000 behind one of my 6v53's. any internal mods to it or are you running it till it wears out.. is your 1000 from a gasser or diesel chevy? was the SAE bellhousing expensive?
Thanks, good work posting and keeping the thread going.. thats a lot of work too.
Thanks, again!!

The trany is a diesel one.It is out of a 06from behind a Duramax.Has a shiftkit from Goerend brothers.A freind of mine works for a Allison dealer did some other modifications to the front plate between the bellhousing and the trany body.Will be useing the 06 TCM and BCM and a Cat.TPS.MAXPF worked this out.I haven't fully made my mind up yet if I am going to make my own harness are by a stock one and strip what wires I don't need.
The bell housing was like $175.00 I think I got some other thing to.I didn't think that was to bad.I had all the rest of the parts like the SAE motor houseing and flywheel came with the Perkins Phaser.
Allison will not make a Stand olone TCM for the 6sp.1000ser.Because of liability reasons.
I'm going to box in the fram from the front radias arm bracket to were the frame starts to make the curve up under the bed.I want to someday put air rid in the front like the rear.Money is a little tight at the moment.laid off from my job for the winter till March first time for that long in 24 years.I for got to list all what has been done to the truck at the beginning of the thread.Will do that later.

Does anyone have a wiringharness for a 06chevy allison.while the motor is out I'm going to put some Dynamat sound deadning on the out side firewall also.I have it already on the inside.When I put the Vintage heater and A/C system inside.Made alot more room on the firewall in the engine conpartment the original ford stuff was in the way for the bigger twins.Made it look alot cleaner.

Looks good Dale. I believe the first time I ever saw your truck was on Diesel Central about 10 years or so ago I guess. It's always been an eye catcher.
