Default Drain plug torque

So it started as "what torque should the oil drain plug be". As I try to find an answer to this it also raised the question about the pan bolts.

Can someone tell me what the torque should be on both the drain plug and the oil pan.

T.I.A.

Default Re: Drain plug torque

oil pan bolts = 20 ft/lbs or 26 N/m
oil pan drain plug = 37 ft/lbs or 50 N/m

Just about ALL of the bolts I've removed on this motor for various reasons, from breather bolts to IH bolts, the plenum, and you name it bolts, have been loose. All of them are now torqued with a dab of Locktite (blue for everyting except red LT on the flywheel) threads. Now they seem to stay put pretty well - no leaky.

As for the steel/aluminum contact between the various plugs and the pan and the transmission, for examples, I reinstalled them with Neversieze or teflon tape; the latter is prolly best to prevent seepage during temp cycles.

Just a thought.

Thanks guys, on that note, headers are going on the car as soon as they come back from Swain Tech. Tourque on those? Lock tite?

Unless you pull the motor you will not have sufficient room to even consider using a torque wrench. You will most likely be using a small box end wrench and limit of torque will be determined by pain threshold you can deal with.
As for the loctite, I did not use any.

Always use Stage 8 Exhaust Header Bolts with locks (Headers Only). Do not have to torque the Header Bolts too much as the locks will assure the bolts do not loosen (torqued header bolts into aluminum which area gets very hot makes removal of bolts at any time difficult. Use a bit of antiseize on Header Bolts with the Stage 8 Locks). Also use a bit of antiseize on all spark plugs.

Header Bolt Kit

Only works with Headers however as the individual locks use the header pipes as a stop. You do not need a Header Bolt in EVERY threaded hole. On my installation of SW Headers, removed the motor mount insulation each side as the insulation on top of mount was touching the headers.



On Cam Covers when SS Bolts are used I now use no loctite and no Antisieze using the Aluminum Stat-O-Seal washers. The Stat-O-Seal Aluminum washers with molded Buna-N inner seals are much more reliable than the more common steel stat-o-seals. The Stat-O-Seal Aluminum Washers act as a bolt sealing and locking mechanism. I use no Loctite or Antiseize on the Plenum SS bolts as the Plenum may be removed from time to time.

If the rubber portion fails to make contact all around the port, the aluminum will act as a crush washer, providing a reliable metal to metal seal. Use them to seal screws, bolts or plumbing fittings. The Buna-N seal is resistant to petroleum fuels and oils. Pegasus Auto Racing



There are several opinions on this but I have always used a thin coat of Permatex on water pump, oil pan and oil filter housing gaskets (both sides of gasket). I always use a thin coat of Permatex on the oil pan drain plug and differential drain plug also. This not only helps seal the plugs but also acts as a thread locker (A little less bolt torque with a good sealant) .



The best LT5 Metric Tool set is the Flex Head Ratchet Set.
The 8mm works great for the Battery Terminals.

As always, Cliff... you have a talent and are an asset to the group!

Thanks D, I'll pick up a set. The torque chart would not open.

Give the chart another try, it opened with no problems for me.

Loctite 242, 243 & 262 is only rated to 300F. Heat is used as an aid to dissassembly. Vibration is the cause of fastener loosening and only occurs under running conditions. I haven't checked the actual, operating temperature of the cyl head at the exhaust port, but I would expect temperatures in excess of 300F.

Considering the difficulty of accessing header bolts and the small tools used, I would not recommend the use of Loctite on header/manifold bolts. It could make disassembly problematic.
