Installing Oil Pan Gaskets

Here's a tip that worked for me -
New pan gaskets don't lie flat where you want them to and it's difficult to line up the holes, so do the job in stages.
Starting with the lower pan, apply a smear of gasket cement with your finger around half the pan.
Lower the first gasket onto that half, lining up the holes and press down firmly, applying weights to hold the gasket down.
When the cement sets, do the same with the other half.
When totally dry, smear cement right around the top surface of the gasket and drop the drip tray on top, aligning the holes, pressing down firmly.
After that has dried, do the same with the second gasket as with the first, fixing it one half at a time.
When everything is completely set, make sure all holes are clear and trim them if not - you don't want to find out the holes in the gaskets are misaligned after you've filled the oil troughs and are offering up the assembly because it's happened to me twice with ROC pan gaskets.
When you're ready for final assembly, put a smear of cement on the engine block, not the upper gasket.
Get a friend to help you offer up the pan using the 4 long bolts method ( not your spouse/partner who'll take offence and retreat into the house when the swearing starts as you start to raise the oil filled assembly and the oil slops around - like Mrs Fogey did ! ).
If you have one of those big oil syringes, when the gap is still a couple of inches, go around the gap squirting in oil to fill the troughs and wipe any drips off the gasket with brake cleaner - it's much easier than trying to lift the pan up with the troughs filled.
Then take the pan right up and insert the short bolts and then remove the long bolts and replace with the remaining short ones.
Job done !

It's not the quickest way of doing it but it minimises the risks of getting into a mess.

    Totally agree, especially with the choice of assistant.

    To keep the gasket stack and trough in place, I have tied it to the pan with sewing thread through every second or third hole. After you have most of the bolts in, snip the threads and pull them out, then tighten it all up.

    The old glue the joints to the grease. This is what I will do when reassembling with a help of a bottle jack and a hold as during the demounting.
