    OK...

    everybody and everything I read tells me that I need to install a new nylon bushing with the oil pump shaft... anyway I've got a new bushing, and I'm looking at the oil pump shaft that the distributor ties into and it doesn't look right...

    where exactly does this bushing go??? (and don't tell me I'm gonna have to pull my oil pan to install the stupid thing... because if that is the case it won't happen unless it is cricital)

    Doh! Jeff that goes between the shaft and the oil pump! Not the shaft and the distributor. You need to take the oil pan off [​IMG]

    That was what I mentioned before, you can get a new shaft with a steel sleeve (bushing) instead of the nylon one, because over time the nylon ones are prone to cracking, and that can cause them to fail. The ones with the steel sleeve are fairly inexpensive, so it is cheap insurance.

    Re: question on new bushing for oil pump

    oh I remember you mentioning that, but being my first time in there I had no idea where it went... there was not a bushing the oil pump that came out of the old block... when I got talking to the parts store they told me it went on the shaft between the oil pump &amp; dist. so I went ahead and put it together (they didn't have the bushing)...

    well now that I have the bushing &amp; I'm trying to get it on it is not working... [​IMG] (they didn't have a bushing here that wasn't nylon, not much of a choice there)

    Re: question on new bushing for oil pump

    Nope, parts store is mistaken, the bushing holds the oil pump shaft to the input shaft on the oil pump, and the bottom of the distributor gear slides over the top of the shaft to hold it there. So you have to drop the oil pan, take the pump off, put the bushing and shaft on the oil pump, then put the pump back on, slipping the shaft up through the clearance hole, and bolt the pump back on. Then when you drop the distributor down through the intake the distributor drive gear will slip down over the top of the shaft. You may have to turn the shaft to get the distributor to drop down on the shaft (because the distributor turns as it goes down in).

    Re: question on new bushing for oil pump

    OK...

    now I am totally confused... [​IMG]

    took my oil pan off, and I get the pushing put on the shaft coming out of the oil pump... (there is a ridge in the bushing, and it is clear where those 2 go togethers...) but I'm looking at the shaft that goes to the distributor... there is,k what looks to me, a metal sleave that has a pin that goes through the top. this sleve does not appear to come off from what I can determine.

    so where do I go from here??? right now I am left assuming that this depends on the oil shaft you have... some with a permanent metal bushing, and others with a replacable bushing...

    Re: question on new bushing for oil pump

    man Kron, I kinda hope that isn't the case because I had an increadibly good seal on that oil pan, and I'm not sure if I'm gonna have to replace my gasket or not...

    I used some silicon sealer on it, and the gasket I have for the oil pan it one solid continuous ruber gasket with metal in it on the sides... well the silicon stuck to the gasket, and I can't figure out a way to clean the stuff off so I can re-seal it. now I gotta decide to just do another seal over the existing silicon (don't feel good about that one) or get a new gasket... [​IMG]

    I'm gonna bring this gasket in tonight &amp; go through it with my hands and see if I can pick all that crap off (or at least most of it).

    Taken from a Jegs catalogue," The unit features a special pinned steel sleeve to maintain correct alignment between oil pump and shaft, which is far superior to the brittle, stock plastic sleeves."

    Hope this relieves some of the paranoia! LOL

    Re: question on new bushing for oil pump

    oh... man I wish I'd have know that bit of information before I pulled that oil pan off... [​IMG]

    man I've never seen a gasket like I've got sitting here, and I don't know if I can find one out of the head kit, but I really like it! (man hope it isn't spoiled... this thing is a pain in the butt to clean up! [​IMG])

    Re: question on new bushing for oil pump

    just got done looking at the car quest web site (where I got the head kit) &amp; it looks like this is a pretty standard gasket for them...

    think I'm gonna go up there in the morning, and see if I can pick one up! [​IMG]

    let me tell ya guys, if you gotta do an oil pan try car quests oil pan gasket! I'd bet there isn't an equal on the market... (these are manufactured by VICTOR REINZ, a division of DANA...

    Re: question on new bushing for oil pump

    Double Doh!!! Your oil pump driveshaft already had the steel sleeve and you didn't realize it? Aww, that sucks! Sorry, Jeff, if I would have known that... well at least you know it is right now, better to have tore it apart to be sure that to have it be wrong [​IMG]!

    Those gaskets are top of the line. They should have plenty in stock for a replacement. I should know, I work for Dana!

    Re: question on new bushing for oil pump

    hey,

    maybe you can answer this then... when I'm using this gasket do I need to use a silicon sealer, or just use the gasket its self. I'm assuming all I would use is the gasket, but I figured better be safe then sorry so I used a RTV high temp silicon on it... man you cannot believe how that gasket sealed!

    Re: question on new bushing for oil pump

    You shouldn't need any silicone if its a one piece oil pan gasket. It can actually defeat the sealing characteristics of the gasket if you use silicone. It can cause the gasket to get pushed out the sides which could cause a leak.

    Now, if its a muliple piece oil pan gasket set a little silicone at the corners may be needed but, not on the entire gasket surface.

    If you have any more questions about gaskets or engine parts I should be able to help. I work at Clevite Engine Parts so I can ask around here at work or look up some info for ya.
