MG MGB Technical - Lubricating cylinders when turning over engine
How much oil should I put down each bore when I turn over the engine of my garage find? I've turned it a little on the crank nut just to determine if it's seized (it's not) but don't want to risk turning any more unless there's some lubrication there. |

Steve- A tablespoon of oil should do the job. Give it a little time to ooze around the piston rings. |

Steve.. That's correct a tablespoonful in each cylinder will do the trick. Sandy |

To make this task easier, go to your local farm supply and purchase a 60cc syringe in the vet med section. A tablespoon is equivalent to 15cc. Draw up the oil...squirt it into the cylinder bore. |

I have syringes. I use them for refilling my printer cartridges. I'll liberate one for this task. |

As much as you like. Spin it on the starter to blow out excess before cranking with plugs in or you could get too much compression pressure. |

I use a canister oil pump dispenser for this. I give each cylinder 2-3 shots of the trigger. Although I've never actually measured the quantity of oil that I use I think that it works out to about 2 tablespoons. Then I let it sit for a few hours (or overnight). Before cranking (no spark plugs installed) be certain to drape a towel on the sparkplug side of the engine. Use spring-type A-clamps to secure the towel. It'll help catch any oil spray from getting all over you, the engine, and fenders. |

Since they have dished pistons, I would put in more than a tablespoon. I think it is something like 11 cc dish for low comp and 5 or 6 for high comp. I often use something in a spray can too so that it can mist the walls. I would also remove the valve cover and pour oil over the rocker assy and pour it down the push rod holes. Then I would turn it by hand before I turned it with the starter. Charley |

I have just bought a 1974 V8 that has been stood since 1986 and was last started 3/4 years ago.I was intending to oil the bores befor starting but as the engine is in a v configaration the oil will only sit at the bottom any sugestions as to the best way to oil up. |

If the engine has stood a long while then a squirt of diesel left for a couple of days will help free any stuck rings but otherwise I really would not bother with oiling the bores - if the engine turns then just fire it up. |
