msmithmmx Posted September 30, 2007 Share Posted September 30, 2007 OK, I am in the process of removing the cam seal and it will not come out. I have torn it somewhat and it still will not budge. Any tricks, I soaked it in multiply penatrating oils with no luck. Help Please Quote Link to comment Share on other sites More sharing options...
stevetone Posted September 30, 2007 Share Posted September 30, 2007 OK, I am in the process of removing the cam seal and it will not come out. I have torn it somewhat and it still will not budge. Any tricks, I soaked it in multiply penatrating oils with no luck. Help Please I just did this last week. On mine, I used a screwdriver and punched it out from the back, being careful to avoid the housing. Yours sounds like it must be in there much tighter -- good luck! Actually, your housing seems deeper than the one on my engine? Maybe the screwdriver won't work... Steve Quote Link to comment Share on other sites More sharing options...
idosubaru Posted September 30, 2007 Share Posted September 30, 2007 drill a carefully placed pilot hole with a thin bit, then use a self tapping sheet metal, or other, screw. once the screw grabs, use a hammer under the head of the screw to pull it out. or buy/borrow a seal pulley. screw drivers work, just don't score anything yo'ure not supposed to, that's easy to do.

porcupine73 Posted September 30, 2007 Share Posted September 30, 2007 Where you can remove the cam cap, I just use a regular seal puller like from napa and it pulls right out. On the RH side where you have to pull the cam seal in place over the cam, the only method I have had work is to drill two small holes in the seal, screw in two small screws, and use pliers to pull the seal out. Nothing else seems to budge it. This time on 2.2L I tried some pullers and stuff and gouged the heck out of the cam which I could not smooth out even with 400 grit sandpaper and scotchbrite; hopefully it doesn't eat up the new seal.

msmithmmx Posted October 1, 2007 Author Share Posted October 1, 2007 I got it out with a thin flat head screw driver. I banged it between the housing and the seal. I have a little pit but not on the rim that counts. The next question...... How do I get the new one back in.... Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 1, 2007 Share Posted October 1, 2007 New one goes back in with a seal driver if you're driving flush, or a 1" schedule 40 pvc female/female joint adapter (any hardware store) works great for me. These can be tough to get in straight, at least in my experience, this is probably my least favorite job so far in automotive work. Make note not to drive too much further than the original is installed. Quote Link to comment Share on other sites More sharing options...
avk Posted October 1, 2007 Share Posted October 1, 2007 Perhaps whoever installed that seal had put some sealant on the outer side? There were some old threads about this. What works well is to pry on the seal lip with a tip of a screwdriver leveraged against the cylinder head. A piece of wood can be placed between the screwdriver and the head to obtain the best working position. Then there's a Craftsman seal puller tool, which can be viewed as an ultimate adaptation of a screwdriver for the purpose of seal removal.

porcupine73 Posted October 1, 2007 Share Posted October 1, 2007 I got the craftsman seal puller; some people say it works great. I couldn't get mine to budge with it but did manage to scratch the cam with it. Quote Link to comment Share on other sites More sharing options...
OB99W Posted October 1, 2007 Share Posted October 1, 2007 Lisle Corp makes various pullers, some of which are sold by Sears. I don't have one of these myself, but it looks interesting: http://www.lislecorp.com/tool_detail.cfm?detail=1438 Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 1, 2007 Share Posted October 1, 2007 Nice find OB99W. That does look interesting and just crazy enough to work! Looks like they go for $15-$20. Quote Link to comment Share on other sites More sharing options...
OB99W Posted October 1, 2007 Share Posted October 1, 2007 It apparently lists for $17.95; some Google searching turned up the following: http://www.sjdiscounttools.com/lis58430.html http://www.tool-home.com/products/catalog/product_info.php?products_id=7270 http://www.tooltopia.com/index.asp?PageAction=VIEWPROD&ProdID=29316 Obviously, any shipping charges would be additional.

avk Posted October 1, 2007 Share Posted October 1, 2007 I got the craftsman seal puller; some people say it works great. I couldn't get mine to budge with it but did manage to scratch the cam with it. I believe the trick is to push the tip away from the shaft when inserting it under the lip. But maybe it's easier said then done. On the right side, I did leave a mark on the camshaft but it was near the sprocket end. It may not be the easiest tool to use, for sure. Bought it because I thought it would be better than a screwdriver, and an "ice pick" type wouldn't fit.To gain more room for maneuver, I had to remove rear timing cover. The current Lisle puller might be an improvement of that design. Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted October 2, 2007 Author Share Posted October 2, 2007 Two questions ,,,, 1) When installing the new seal do I coat the sides with a grease (the manual says to apply grease), what kind should I use. Also, 2) do I need to use a blue thread locker? Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 2, 2007 Share Posted October 2, 2007 I put grease on the oil seal lip, all over it, to help prevent it from folding over on installation and give it some lubrication. Usually I put a little engine oil on the outside of the seal to help it drive in otherwise it can be a little tight. Sometimes I use RTV if I gouged up the hole the seal will sit in. Permatex grey gasket sealant (not ultra grey, though that would be good too) seems to work well. It is liquidy but when it dries a little it is kind of tacky, so it helps the seal go in then holds it in while sealing. If too much lube is on the outside of the seal, it seems to make it more likely to 'tip' on installation, like the bottom will suddenly go in way deep and the top will pop out.

porcupine73 Posted October 4, 2007 Share Posted October 4, 2007 Nice find OB99W. That does look interesting and just crazy enough to work! Looks like they go for $15-$20. Ok item arrived today. It does look promising. Here's some pics. I'll try this out on my '94, the next maintenance project I have involving cam seals this winter: Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted October 5, 2007 Author Share Posted October 5, 2007 OK I am sold, the guy only has 3 left now. Hmmmm I wonder why... Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted October 10, 2007 Author Share Posted October 10, 2007 WOW, I just recieved that tool. I pulled out the passanger side cam seal in 10 seconds with NO damage to anything. This was well worth the 17 bucks I paid Quote Link to comment Share on other sites More sharing options...
frag Posted October 10, 2007 Share Posted October 10, 2007 1) Nice tool. Where do you insert the blade of that tool, between the shaft and seal or between the seal and seal hoder? 2) One way of doing it more easily and without damage with a screwdriver is taking a cheap blade screwdriver and bending the tip slightly to one side. Insert it between the seal and the shaft while straightening the handle toward the shaft getting the tip of the blade AWAY from the shaft. It's the tip of the blade that scores the shaft. Then, taking the lip of the seal holder as a fulcrum point you push the handle down, taking out the top part of the seal. Quote Link to comment Share on other sites More sharing options...
avk Posted October 10, 2007 Share Posted October 10, 2007 I guess it goes between the seal and the shaft, where's there no reinforcement. Same as their previous tool, or indeed the screwdriver. Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted October 11, 2007 Author Share Posted October 11, 2007 Seal and the shaft, the good thing is no damage due to a slipping screwdriver. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 11, 2007 Share Posted October 11, 2007 Yes, scratching the cam isn't fun. That is some hard steel in there. I worked away at my scratches with emery cloth and then fine scotchbrite but couldn't get the scratches completely out. I worked at 'em until they at least didn't feel like they would eat up the new cam seals. Quote Link to comment Share on other sites More sharing options...
