I just had to do this yesterday on my 98. To anyone who is replacing this part, you have to drop the oil pan because the oil pan gasket over laps the timing cover.I tried to just push it in like the video but 100% will not work. Drain oil, drop oil pan, then remove timing cover. Not trying to be rude.
This video does not have enough information to seal the cover at the oil pan. Did exactly as he did oil is spraying out where the cover meets the pan. Don't torque the bolts to 18ftlbs on my 1997 it's 100inlbs. I no longer trust 1A Auto!
great video but, thank u for the torque specs, i feel like 18 ft pounds was too much, i keep choosing a lower torque seting, but one of the new bolts was already busted due to over tight and ending braking inside the engine block. i will have some fun time removing it.
They do to much in the replies of "thanks for the feedback". They need to go to school, and learn how to do it the right way. First time watching them. Not again. Doing this work for 50 years now.
I've done my twice now with 387 thousand, and doing the 3rd time right now. You do need to clean pan and block at mating places. You need new drop pan without removing bolts. Will give just enough room to replace cover.
Wish there was a better angle of yall fitting the timing cover over the oil pan gasket, id like to know how he did it. I have done my oil pan gasket previously and there is no way to get the cover to seat correctly with the pan still in place. Hoping I wont have to take the whole pan off and can just drop it down a little. (my trucks a 2000 5.7 obs)
I broke a bolt while torquing to 18 ft-lbs on my 99 Suburban 5.7L. My research lists the torque specs as 106 in-lbs but I've also seen it listed at 6 ft-lbs. Make sure to double check the torque numbers on your vehicle.
I used a digital torque wrench to remove the bolts just for this reason. They broke loose between 8-10 ft lbs ,, generally closer to 8ish on every bolt.
did you just have to loosen the oil pan or take it completely off? What year is your truck? I'm getting ready to do mine tomorrow, my truck is a 98 just seeing if yours is a different year mabey its a little different. Thanks in advance.
****raises hand***......, also, didnt know there needed to be a gasket on the oil pan. I replaced it the cover and it leaked, took it to a friends shop and they did the same and it leaked. Found out today the gasket was missing, but this video never said anything about the gasket.
How come everyone says you have to drop the oil pan a little to remove and install the cover because of that bottom lip but the covers in the video popped off and on without any problems?
I ran into this issue. The lip broke on my old cover when I removed it and the new cover would not install. I considered loosening the oil pan but decided against it. I ended up sanding the back edge of the lip down so that it was flush. It then installed fairly easily. I'm still working to install the heads so I have not had a chance to start the engine and see if the modification to the cover will cause a leak...
4.3 is a lot easier to work on with less stuff in the way, mine doesn’t have AC either so it’s a breeze. Just make sure to seal the whole surface completely and don’t over torque the timing cover bolts
I missed the part where antifreeze was removed first. Those cover bolts ARE ABOUT 1/4-20 SIZE so 6ft-lb to 10ft-lb is a more appropriate range for torque. Basically sung enough they won't come loose is all you need.
@@TNsher776 If it's the plastic cover, those are shoulder bolts so cracking the plastic most likely won't happen. The bolts only need to be tight enough they can't rattle lose. Sometimes the rubber gasket material isn't quite thick enough and using a thin flat washer under the bolt head will push the cover closer to the block to make the seal. Use as thin a washer as possible to avoid cracking the cover and this will often stop an oil leak coming from under the cover (often near water pump mounting surface). If you have no leaks then leave well enough alone, it'll be fine.
@@thisisyourcaptainspeaking2259 No leaks around the cover I installed, the problem I have, oil is leaking around the crankshaft seal, I replaced the harmonic balancer with a brand new one, I thought that might fix the leak, but still leaking around the seal. I believe I may have damaged the timing cover seal when I tried to install it while the oil pan was in place, the seal possibly may have gotten damaged on the crankshaft key. I didn't put silicone around the crankshaft key and the harmonic balancer, do you think that may be causing the leak? When I first took the balancer off (that would've been the first Time ever for the truck) I noticed it had silicone from the factory around the crankshaft harmonic balancer key.
They make putting the cover on look so easy and won't answer any questions on the lip at the bottom. I'm going to grind mine down I suppose. I only paid $32 for my dorman cover at advanced auto.
@@1AAuto unrelated to this question, but I cant get timing cover on on my 97, the lip wont go into the oil pan. Did you have to lower the oil pan to get it in ?
@@1AAuto Is this the same procedure for the 4.3L V6? I can hear my timing chain a little bit. It still runs good,I just want to replace it before it becomes a problem.
1 more not so much related question but if I remove my oil pan to replace that gasket would it be best to also do this gasket at the same time and is the an order as to which I do first and last (oil pan and timing cover)
I have a vertical crack down the middle of timing cover. Would this cause a coolant leak ? Thought there was oil behind the cover not coolant. Chevy silverado 1500 5.7l and cover is plastic. Have a heavy coolant leak which I thought was water pump which I removed but can't see any problem with it or hoses. That is when I noticed cracked timing cover.
i replaced mine, it dosnt leak at idlr or reving the gas, but on the road i have a leak, i used a whole tube of sealer, whats the issue? clean it and apply more sealer to see if it stops?
Is this the same process for the 1996-2000 4.3L V6 engines. The V6 engines have a cast aluminum oil pan. Other than that they look pretty similar. I think they use the same timing cover.
+Tom Caffrey We don't have a how-to video for your vehicle right now, but the basic steps in this video should be enough to do this task. Buy this part for your vehicle on 1AAuto.com: 1aau.to/m/Shop-1AAuto-c
I'm doing the same thing on my motor now I see a difference in the timing chain cover New and you distance stalled The new one you this stalled Is different than the old one you took off What I mean by that is on top of the cover looks like a Handel And the old one don't have it
from all the negative feedback and comments @1aauto ought to pull this video with apologies and even condolences to some and either reference another more skilled mechanic doing it right or just stick to selling parts not ill-advised “I don’t know-how,” I mean wtf, guys? home lame.
13miniutes in he says 18 ft lbs on the timing cover. It's not 18 ft lbs it's 6ft lbs. Don't torque to this setting cause it will break your 10mm timing bolts. Double check your specs. Cause this is wrong advice. I wish I double checked before going off this video. I even bought a new torque wrench for this. Now I have to extract a bolt from my block.
+Randy Nolan If you are reusing the old cover. You should clean up the old gasket material and put a new gasket or sealer in place. Hope this helps you out. 1aauto.com
1A Auto Parts I'm using a new one it actually wouldn't go between the tabs on the block where the oil pan and the block go together. I actually had to trim some of the inside of the cover. All is good and works now no leaks. I needed it fixed
It's impossible to install the timing cover without lowering the oil pan!! A lot of guys will try this without dropping a bit the oil pan and they will brake the cover or damage the oil pan seal!! So you should better show the whole work that you did!
@@jordancollins4764 I tried the same thing, I can verify there is a huge ass gap and used up almost a hole tube of rtv so it would stick out enough to seal against the oil pan, there was a 1 piece rubber oil pan seal, I ripped out the front part of the seal that seals against the timing cover and pan because it was impossible to get the cover back on.. and I shouldn't have, I had to use a shit ton of rtv. Next time I will drop the oil pan a little and install timing cover.
yeah something funny is going on here because it's super hard to get those on and off you got a cut on them they come off easy but you got to cut on him to get them on for boats good luck getting to the oil pan
