Thanks for the detailed guide Billy, got both valve cover gaskets and plug seals done on my 6G72, the screwdriver trick for holding the plenum chamber up worked great, was tricky lining up the rear valve cover bolt holes with the limited access but we got there in the end
Thanks for the kind feedback @thenewzealandben, happy to know that the video helped out it. Indeed getting the seal to remain in place on the rear rocker cover while trying to line it up is challenging and I've found a dab of superglue can help. In my latest video going live in a couple of weeks I used a rubber mallet to hold up the chamber to change the spark plugs which was equally effective at creating enough space to work.
Indeed it is, but this country is practically a police state with all of its rules and regs. In NSW it's required annually once the vehicle is more than 5 years old. I find it an inconvenience as it is, and can't imagine owning several cars that you wanted to keep on the road. Thankfully, where I take mine doesn't give me a hard time, and you have 6 months following the inspection to renew your registration. It means that I can return the car to storage and renew it when I'm ready to drive, such as from this weekend. It also means however that the registration renewal date changes each year now. Good to know SA and I understand VIC are more relaxed; only required when you want to buy/sell?
Glad to hear that it can help you out, my pleasure. 👍 About to start editing and post a detailed video on replacing the heater core, a common problem on these.
@@leecasey3022 😄Woodchipper, I like that, mine sounds the same. I have a week off soon and can probably do a video on that as mine also needs changing.
Thank you that was very informative. Pls show how the upper mount struts and the timing belt are replaced. I am not a mechanic but would like to know about different processes
Hi. Ebay prices vary from $19 to $99 for the 6G74 rocker cover gaskets. Some are black and some blue. As I won't be keeping the car for much longer should I just go with the cheap black seals?
Hi Peter, I’ve purchased quite a few sets from eBay over the years, usually the cheapest set (front and rear) available given the motor’s propensity to leak and found them to all be pretty much the same quality, black or blue. I think what determines their longevity more so is ensuring that the covers are torqued down correctly.
Hey Billy is there a chance i can get away eith replacing the rear rocker cover and plug seals only? The front on my Magna looks dry. My Engine has started running rough due to oil getting down into the plugs
Hi Grant, in my experience it is the front rocker seals that start leaking first so if in your case they're dry then I don't see why you can't leave them be and only replace the rear seals. I actually recently did just this, but I replaced the front seals, and documented it in my online service log book so that I can keep a track of which seals I've replaced and when.
Hey mate have you got a photo of the face of the distributor where the leads go in? Stuffed up the order of the back three and can’t find a diagram anywhere
G'day Hydro, the distributor cap is numbered, so from the top, going clockwise: 2 1 6 5 4 3. The firing order on each bank is as follow, when standing in front of the car looking at the engine: Rear bank left to right: 1 3 5 Front bank left to right: 2 4 6 Hope this helps!
For sure, mine was second hand as they only came standard on the AWD, Sports, VRX and Verada models I believe in the TJ Series. Unsure how much luck you'd have at a wreckers these days but if you search eBay 'magna engine cover' there are still a handful available.
Hey Billy. When tightening the bolts on both rocker covers I was planning to just firmly hand tighten them using the long extender bar with the attached socket. Obviously I don't want over tighten them but I don't want to tighten them insufficiently. I don't have a torque bar. What do you suggest? Thanks.
Pinch tight should be ok, you’ll get a feel for it. It’s what I’ve always done, but just make sure you go over all of them a few times because as you’re tightening one the adjacent may no longer be tight enough but in doing this you’ll be able to get them all relatively evenly tightened but not overly so.
Excellent video. I think this is the same for 2002-2005 Magna as well, right? Also it would be great if you can do a video of replacing head gaskets for these cars. Cheers
Hi Billy. I have removed both rocker covers and removed the old gaskets. They were so hard, like plastic. Hard to remove too. The rear rocker cover groove is wider than the gasket in places. Is this a problem? Should I squeeze it a bit, to make a better fit? Thanks.
Hi Peter, they’ll eventually become hard and brittle with age and you’re welcome to squeeze the cover channels together gently to ensure a better fit for the gasket. They usually spread as a product of being torqued down too much. Even better if you’re able to find a new set of covers but I’ve not had any luck as I’d like to replace mine because the gasket channels are quite uneven now.
Hi billy, just a quick question, I have to do the rocker cover gaskets replacement on my Magna , but on my car there is leak coming from cam thrust case as well. Have you ever changed it before ? Does the cam thrust case comes with the O ring?
Hi Hind, can’t say that I have. I’ll take a look at mine and if it’s leaking make a video on replacing the o-ring. Doesn’t look to be a complicated job.

Rocker cover seals replaced. Mission accomplished. Thanks Billy.
Nice one, glad you got the job done Peter, it’s pretty a straight forward diy even with the rear bank being a little more difficult to access.
Nice vid mate. Upvote for 'Scamdemic'
Thanks Kalon, early on there was just something about it all that didn't sit right with me, and sure enough...🤔
I can't believe there's a yearly rego inspection! How draconian. Come to SA magna brother.
Indeed it is, but this country is practically a police state with all of its rules and regs. In NSW it's required annually once the vehicle is more than 5 years old.

Thanks for making this video Billy it'll come in handy for when i need to replace my spark plugs if not the rocker cover gaskets . Well done 👏👏

@@billymasonpi I'd love to see a blower motor replacement video. People think I have a woodchipper in the glovebox....

@@billymasonpi brilliant, I look forward to it.

Cool. I need to replace my injectors so pulling the Manifold off was the first Issue.
Nice one, glad it helped David.
a light smear of grease holds the gasket
Great idea, thank you! I'll try this next time.

Thanks Kamalini. I have a video on changing the front struts here (watch from 11 min): ua-cam.com/video/u-6mdKnnP0o/v-deo.html
And I haven't needed to do my timing belt, but I found a comprehensive instructional video about it here: ua-cam.com/video/hZp7Et4J5ak/v-deo.html
