how do you guys prelubricate your engines after installation without a prelubricator, because i dont have one and my crank just got machined and i got new bearings and they were wiped out when i started my car after reassembly last time instantly and i need a safe plan : ) i cant afford to make a mistake lol ill be reinstalling after i finish reassembly of engine in a few weeks (cranking for pressure no plugs?) thx

Weve used a heavy oil (20w 50) for bearings and such. Not sure what year car you have, but if you have a 2G.. you can pull the "moteur" fuse in the fuse panel under the hood, and that will prevent spark and fuel upon cranking. This will build oil pressure to assure proper lube before starting.

What exactly have you done to rebuild? Just the repolished crank and new bearings?

Well....after you assemble the engine and right before you put the timing belt on....fill the engine with the proper amount of oil and use an impact wrench on the oil pump to spin it for maybe a minute full speed clockwise.

But, we assure you that oil is moving, so you dont have to take off the valve cover like I did to check.. Oil goes EVERYWHERE :o

yeah, the valve cover doesn't need to be bolted down, just needs to be sitting on top to keep the oil from hitting the ceiling of your garage.

on a 1g you can pull the ignitor (its a ceramic looking box with a plug on the passenger side mounted in about the middle of the firewall at the top) Just pull the plug and then crank the motor until the oil light inside goes off. Thats what I did when priming my new turbo with oil before actually starting the car. -Tristan

yeah....but....you are cranking the engine while you are doing that. When we are spinning the oil pump, the oil pump is the only thing that is moving in the engine. The whole point of pre-lubricating is to lube all of the critical parts before they are rotated (like with the starter).

For a new turbo application that might be OK.

I have actually seen a guy seize a camshaft from lack of lube by cranking the motor. The oil pump failed to prime before the assembly lube wore off. By cranking the motor he seized the cam, jumped time, and bent 8 intake valves. Bye bye new motor. I always use a cordless drill with a 14mm socket. The impacts can work, but be careful not to strip out the 14mm nut on the oil pump shaft. I have seen them strip out the shaft if the impact is too strong or the oil pressure causes too much resistance against the impact. The regular drill applies a steady, constant pressure to the nut and hasn't shown to cause any side effects.
