1970 1.7 L, in nearly six years in restoration, I've got my engine ready to start on the test stand.
I have the fuel rails primed. Electrical has checked out OK. Just wanted to get group thoughts on what they do ? Turn engine over to prime oil pump or just start it. How long to run it initially, and how or should I vary engine speed much , and to what extent ( rpms)? Also do I change oil immediately after "break-in". What do I need to be concerned about ? Besides everything !!! Engine is nearly stock (slightly higher compression pistons) with original FI.  |

Prime first. Do not fill oil filter. I use a mechanical oil pressure gauge. If pump is new you should be able to get above 30psi. crank for a few seconds and let the starter cool. Once you have oil pressure fire it up and follow cam manufacturer suggested break in procedure.

A gauge is an excellent suggestion.
But .......you can get by with just your oil pressure switch. Attach a test light lead to power (+12V side of coil) and the other lead to the spade of the OP switch. Remove spark plugs. Crank engine for 15 seconds at a time until the test light goes out. Reinstall plugs. Start it up ! ......listen ! |
