I think your gonna come out of this OK. First find the preload and check the geometry & post what you find. I dont think you generated more than the normal amount of shavings that happens during breakin just from the lifters clattering. Might just need a pushrod change. When the time comes cut 2 strips of paper for a ruler & turn the crank till the timing mark is 2&17/32" (40 deg) past TDC on #1 compression & spin the drill to preoil/confirm oiling to the pass side then turn the crank a bit further clockwise to 5" (79 deg) BTDC #6 compression & preoil/confirm oiling to the dr side. continue turning the crank a bit clockwise till it is at 15 BTDC for a wild cam or 10 BTDC for a mild cam & time the dist to the #6 plug wire if the dist has been removed for this.

Reference using 273 rockers with a hydraulic cam.

You just have to adjust them correctly. The T/A engine used adjsutables with hydraulic cams.




They did not use 273 pushrods did they?


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Not sure on that one, I did build a 273 a few yuears ago with a hydraulic and I used the original push rods and rockers.


Careful, your character's showing!

i would guess switching to to 273 rockers could handle as much as .050 difference in push rod length.

If you're taking covers back off, take a look inside them too for any funky marking. Especially aftermarket ones.

Are the rockers, push rods and top of the head covered with oil? I would want to rotate the crank while running a drill and make sure everything is getting oil prior to restarting for any reason. With that amount or run time you should have oil everywhere. I used stock 273 rockers on the Eddy heads with 0 problems but mine was in a solid lifter application.

I may have missed some posts but I didn't see any reference to having the rocker shaft on correctly. If it not installed correctly you will have lots of rocker noise. Make sure that the notches on the shaft is down and toward the front on the drivers side and down and to the rear on the passenger side of the engine. If this is not followed there will be a lack of oil to the top end. It is also possible that all the lifters did not pump up and that shutting the engine back down and restarting will allow them to purge air out of them and to pump up.

OP, how did you set the adjustment preload on the lifters? I'm almost positive that none of the 273 motors came with hydraulic lifters stock, so that means the pushrods you used are for solid lifters, not hydraulics There to long probally All of the OEM hydraulic lifters, both early and late, have a different cup hieght, higher, than the same year solid liftrs cup hieght so the push rods your using are probally to long collapsing the hydraulic lifters The 340 T/A, AAR Cuda motors had a special set of pushrods to make them work with hydraulic lifters, not the same lengths as the 273 solid lifter pushrods Let us know what you find out

68 and 69 273's came with hydraulic lifters, just like the 318.

Ive used adjustable rockers on hydaulic valvetrain many times, just fine. They should be okay for use with any cam, if adjusted properly. As stated above, first thing that came to mind when I read the OP was "The rocker shafts are in backwards". Have you checked that yet?

Hope you never used a one oil hole head gasket and then installed it backwards if that's possible. I believe oil for the heads comes from cam bearings through a gallery in the block , through the head gasket into the head and into the rocker back bone . I believe the oil comes up through the second from front dr. side rocker boss and the second from the back on the pass side . Its been 25 yrs since I built a 340 so I could be all messed up It seems to me its either head gaskets on wrong or rocker back bone on up side down .

All of the rockers are oriented correctly. Already checked that. I primed the oil pump and turned the crank to make sure oil was flowing to both sides through all the passages.

One thing I did notice this morning. The oil is thick, really thick almost like honey. Like to never got it to filter through the coffee filter. I noticed when I primed the pump before installing the motor that the oil was thick and kind of milky then but figured it was because of the cold temperatures. It was about 35 degrees this morning when I drained the oil and it was still just as thick. It might just be normal for the Rotella. I have never used it for break in before but read it is good. I also used Lucas break in additive. I am starting to wonder if a lighter oil with some break in additive might solve the problem. Would 10W-30 ( something other than Rotella) be too thin? I might give it a try tomorrow. Let it run a few minutes and see if it helps. Any reason this might be a bad idea?

Yep, that was before the motor was ever turned. It was cold back when I primed everything. I had my heater on in the garage but it was still pretty cold. I figured to was because of the cold.

if your oil is milky colored then you've got a coolant leak.

The oil still had the same milky color to it this morning when I drained it. My initial thought was it's metal in the oil but I found no metal. I checked thoroughly with a very bright light. It's milky...That's the best way to describe it. I had a motor spin a rod bearing once many years ago. I know what metal in the oil looks like. This isn't metal. The oil is really thick and weird colored. It's brown and milkish.... I don't know any other way to explain it.

You have water in the oil.

I don't think that's it. Like I said the oil was that way before the motor was installed in the car. There was no way for coolant to be in it then. It looks exactly the same now. It's not quite the same white milky color you get with antifreeze in the oil. Plus I don't think it ran long enough to get much if any in it. I'm pretty confident it's not that.

I think from all the stuff I have read and all the input I have received its either the pushrod length is off or the oil was too darn thick. I'm going to check the pushrod length first. If that is OK I will add lighter weight oil with some additive for good measure and try again. If it still has noir atet a couple minutes i will shut it down and go back tot he drawing board.

Do you have the oil plug installed in the valley by the distributor? Forgot one once
Didnt let the lifters pump up on that side.
