The first two o-rings I tried to locate are either missing, pathetically small, or not included. Oil pick-up pipe to the block - there is an O-ring of the required diameter, but it is much thinner than the original. There are no o-rings for the coolant adapter tube. All O-rings included in the kit are in a bag. without marking. It's hard to know what some of them are for, even compared to the original, which is often harsh and flattened. NOTHING like this in the "complete gasket set" waste of money.
