The BJ7 will finally arrive after a complete mechanical refurbish. Hurrah!!!!

There seems to be differing openions as to what procedure to use when starting a newly rebuilt engine. I would appreciate any and all suggestions as to how to proceed.

Please post your 2 cents worth.

Thanks,

Ray
 
I had a spin on filter adapter on my engine, I left the filter off and attached a hose to the nupple that the filter screws onto, I used a hose clamp to hold the hose onto the nipple. I filled the hose with oil and GENTLY as in 20 lbs blew air into the hose. I would turn the crank dampner and do it again. DO NOT LET THE HOSE RUN EMPTY. This will blow air into the engine and blow the oil out. I did this untill oil came out of the oil pressure gauge port. I also had oil running out of the rocker shaft so I know I had all the passages filled. I cranked it up and instantly had 80 lbs oil pressure cold and 60 at hot idle. Skip
 
The assumptiom here is that the rebuilder used the proper assembly lubes throughout the engine. Remove the oil filler cap and using the solenoid button with the igntion off crank the engine until the oil pressure guage registers pressure and you can see oil coming out of the rockers by peering through the open oil filler hole. Pull the choke turn on the ignition and fire her up.-FWIW---Keoke
 
Thanks for the tech tips. Last year I rebuilt my MGA and was advised to take a pump type oil can and pump oil into the line that runs from the oil gaugue to the engine until pressure if felt on the pump can. I then removed the plugs and cranked the engine until the oil gauge registered 40 psi. The engine was then cranked and the engine speed was maintained at 2200 rpm for 20 minutes. I was informed that it was extremely important to maintain between 2000--2200 rpm for the 20 minutes. The reason given was to insure that the cam was properly "beded in". Is this the case with the Healey engine?
 
I know what they say about bedding in the cam to the lifter surfaces and running the rpm`s at different settings and I agree but I have to say two of the best engines I have ever had was one in my airplane ( 0-235 Lycoming) and one in my go kart hauler (390 Ford) and both were started up and run hard. The airplane engine had 20 minutes running time and the hauler about 15 before I ran them out hard. Get the oil and water temps up, vary the rpm`s every few minutes and let her rip. I did the same with my Healey engine and it runs like a 2 dollar watch. Skip (my 2 cents)
 
Do any other viewers have an opinion as to how to handle the rpm range of the engine on inital start-up? Would appreciate others relating how they handled the rpm question after starting their rebuilt engine.

Thanks,

Ray
