Fist, i do appreciate your suggestions and comments, just so you guys know.

But i don't agree on somes points:
1)-i would never run a new engine more than a few minutes for the first
start... just to see if everything looks and sound right. of course hydro
lifter may not be pumps fast the fist time so noise is normal, but they
should pump quickly, i would say 3 minutes at most. Second, the cooolant
system is not bled, so overheat may come form there instead of overheat from
the new engine parts. i would start the van again in the optimal bleeding
position (front raise, bleeder screws open), keeping a good look on the temp
gauge and using an infrared temp gun. Of course, make sure to fill the oil
filter as much as you can before the first start, fill oil as needed after
the first few minutes start.

2)-if the lifter noise is not gone after a few minutes on the second start,
i would check and adjust those. Concentrate on bleeding the van first wile
keeping low temp (am cheking the exhaust temp with infrared gun

3)-this procedure (bleeding) should take about 15 to 30 minutes on the
parking lot, so yeas, the fist 20 minutes.

4)- Time to drive the van, slowly in small street around the house, check
temp every 15 seconds, at any sign of overheat stop the engine. You won't
like the following..... am driving the van with both bleeder srews open for
the fist mile or so.... after i close both and open them every 10 minutes of
so to monitor the coolant pressure and do a proper bleeding, of course, this
is done going up and down an overpass.... if the engine is still overheating
a lot, go back home and get the van on ramp and try to bleed some more.

5)- When bleeding is ok, i hoping for a slight overheating (a bit above the
cooling light), this will be a normal and good sign.

6)-Am not changing the oil yet and far from it, engine have a oil filter
design for that matter.... Bleed again if neccesary and when satisfy, go for
a normal drive of 25 to 50 miles....if everything look normal, go for
another 100 miles+ drive monitoring the temps very often... after that i
would change the oil and filter. Now it's time (when cold) to make a second
lifter / valve clearance check.

7),ake some small 50-100 miles trip inside your AAA /CAA card region, ha ha
ha ha....

Cheers
Ben
