Timing gear cover for Dummies.

[IDIoit]

first allow me to say that I know this horse has been beaten.

im treating this like a straight up rookie that has never worked on a vehicle.
well, because I feel like one.

im ready to slap this on, and because its my third time,
I want to absolutely make sure its my last.

I have permatex's aviation sealant for the timing cover gaskets.

I have Teflon thread sealant for the 4 bolt holes in the middle.

now, for the timing cover to oil pan....
RTV?
I have gray and black.

IP gear housing is bolted and the gear is locked down to ensure alignment.
all my alignment marks are in order.

surfaces are clean and sprayed with brake clean and wiped down.

first order of business.
take the IPGH off, and set it aside.

run a 1/4-3/8" bead of RTV on the oil pan

with the aviation sealant,
brush surfaces of block and cover.
brush surfaces of water pump and back side of the gasket.

brush threads of center bolts with Teflon thread sealant.


allow 20 minutes for it to set up.

install cover, and water pump.

torque to 25 ft lbs

let dry for 24 hours.

RTV ip gear housing, allow it to set up, then bolt it down.

I rtv the 4 center bolts also. I used either black or grey when I redid my front cover cause of an oil pan leak.

Good luck. May the gods smile upon you.

Yeah everyone said rtv on the through bolts which is weird to me since they are not designed to be a sealing thread but I guess they aren't bathed in oil.

Do we need to go find a Hyundai to sacrifice?

 

[IDIoit]

I felt like it went in ok, but I thought the same the last few times...
gonna let it cure overnight, ill finish her up tomorrow.

The 2 top and bottom water pump bolts enter the gear oily side behind the cover. YOU MUST SEAL THESE THREADS. Not a believer... Don't do it and watch the oil leak out past these threads and ruin that clean water pump...

I used a Teflon thread sealant.

Umm
What a timig mark?

I used a Teflon thread sealant.

There are different types of thread sealants.

Some; like plumbers pipe dope http://www.oatey.com/products/threa...nts/great-white-pipe-joint-compound-with-ptfe are mostly lubricants that allow tapered pipe threads to "fuse" together under great torque. These are not a good choice to seal straight cut threads.

Others; like this https://www.permatex.com/products/t...nts/permatex-high-temperature-thread-sealant/ "cure" after assembly and thus can seal a bigger gap between threads. Typically PTFE (Teflon) is not added to these sealers, as a lubricating quality is not needed.

I prefer to use high oil resistant RTV in this application.

 

[IDIoit]

if these 4 bolts do leak, I can always reseal them.

my biggest issue is the water in oil, as long as it seals, ill be ok!

Where did the hotrod in sig line go?
The rtv in threads has never been one of my fav's...
It is a pita to clear out and when it does come out you find it it the worst places.
90% of the engines I have seen an over usage of rtv( a thin film is all thats needed) not oozing down the sides like manny cases we see.
Permatex makes a specific sealent just for this purpose.

Damn Bri' sorry about all this bs .
Keep at it.

Torque on water pump, front cover, oil pan are 14 ft-lb. I am a fan of alignment dowels and they are even shown in the manual for installing the front cover, and make lining up the water pump bolts easy. Looking at the sealant on those Fel-Pro gaskets: do they really think that would seal on it's own?

x2 on the alignment dowels, especially when using aviation form-a=gasket. I make my own by grinding the heads off some smooth shanked bolts.

Our id front gear cover does have a built in alignment dowel plus.. We need to adjust the cover for the correct seal runout. The shop manual explains how all this is done. I'm betting not one of us has ever checked the seal alignment. Same goes for the rear crank seal and plate.

 

[Shawn MacAnanny]

Those gaskets work excellent. Better than rtv in my experience.

Just a thought but maybe check there isn't crap in any of the holes or you don't have a water pump bolt or two bottoming out keeping it from clamping tight enough.

I haven't had the cover off but if there's a dowel and a blind hole I'd recommend he try to clean it out incase it's preventing it from sealing flat.
