Doof 11 Posted October 22, 2008 I'm hoping someone can clarify a question i have on oil pumps. Basically, i've got one of the little black plastic covers that go over the chain and oil pump sprocket...but the pump has no holes to bolt into... The pump was off an XU10J4...and funnily enough the servicebox diagram shows the black plastic thing fitting to the XU10J4 so presumably this pump should have the holes (unless of course i've got the wrong pump, this engine does appear to be a funny one!) Anyone know what pumps have these holes? I want to do everything i can to stop surge and if these help even slightly its worth me getting a pump with the holes, but i dont know which i need! Are GTI-6 pumps the same? Cheers, Lewis Share this post Link to post Share on other sites
Anthony 1,000 Posted October 22, 2008 All XU10J4 oil pumps that I've seen have the mounting holes for the chain cover, although from memory the early engines don't have a windage tray and thus possibly might not have the chain cover either? Otherwise, I'd assume that it's had the oil pump changed at some point in its life. Share this post Link to post Share on other sites
Miles 331 1 Cars Posted October 22, 2008 Yes the early engine's had the casting for the holes but never used, you can drill and tap these out if needed thou Share this post Link to post Share on other sites
