Valve train oiling and over heating
« on: January 30, 2016 - 06:03:19 PM »
 :working:Hello all, I'm  new to the site and was hoping for some insight to my problem. I've just built my first motor, its a 408 stroker. It has a Crane Roller Cam and the Gold Roller Rockers, Eddy heads. Everything is new. The problem or atleast I think its a problem is I dont believe the valve train is being oiled enough, there is oil on the valve springs but it doesnt seem to be hitting the ball on the push rods. The driver side notch on the rocker shaft is to the front and the passengers is to the rear. I have a Melling high volume oil pump as well. I have plenty of oil pressure at idle. Its not making any noise just concerns me a bit. The second issue I have is overheating, it has an Aluminum rad and high flow water pump. I took out the thermostat  to see if I had good flow and it does so I'm  in a quandary. I know its a lot to ask but I figured if anybody knew it would be my fellow Mopar lovers. Thanks in advance.

You mentioned a high volume oil pump, do you have a high volume oil pan? I've heard stories of high volume pumps completely draining a standard oil pan before. Just a thought  :dunno:

Welcome to the site  :cheers:

As for your cooling...If your thermostat is good maybe your hoses are collapsing???

What are you using for a fan , is the timing advanced enough  , are you sure it is overheating ,, what are you using far a guage ?

hand held temp guns are a must
had a miss last weak on my LS1, and checked the header temps,
and one was 30 degrees cooler, and that's where the spark plug wire
was not connecting.

Is the cam a hydraulic roller? Are the Edelbrock heads set up for conventional block to head oiling or are they magnum style and oil through the lifters and pushrods? If they're mismatched, that may account for the lack of oil to the top end.  :dunno:

How many miles are on this engine? Where is the timing set? What carb does it have on it, and how is that set for power valve and jetting?
I would pull the spark plugs and valve covers and have someone turn it over so you can watch for oil at the top end. If you see it coming out there you're fine. If not, the cam bearings might have been put in poorly.

Thanks for your responses. I have a 7 Qt Milodon oil pan, I am getting oil I cut the top out of an old valve cover put it on and ran the car, it just seems to be lacking where its supposed to hit the push rod. It doesn't  have a thermostat,  I took it out to make sure the water pump and radiator were flowing well. Its a Champion Aluminum  radiator and I'm  not familiar with its durability or performance. The water flow seems to be ok. I have taken an HHR electric fan and adapted it to work based on a thread I read. Timing is 8 BTDC. The temp gauge is factory. I'm  running a Crane Cam hydraulic  roller, the heads are Eddy and they oil through the rocker shaft. The carb is is a Holley 750 with vacuum secondaries. It's  strait out of the box, so not sure of the jetting or the power valve. I wanted to make sure everything was working before I address those items. It only has 3-4 hours run time. I think I will put the stock fan and shroud back on to see if that works. Sorry if it seems all over the place, but I was trying  to address all your questions at once. I really appreciate the help.

don't know if push rods are supposed to be hollow or not?

use a thermostat , they will often overheat without one in place .
 I would disconnect the vacuum advance permanently to the dist & advance the timing to 16*
 The HHR fan should be enough air flow so you could eave that in place for now .
Work on tuning the carb , at least check lug color to be sure it is not lean .

A shroud makes a big difference. My engine temp came down 20 degrees with one.
