One of the 300D 2.5T's you got from me had the epoxy fix for that exact bolt - I don't remember which one. On Sun, Oct 25, 2020 at 11:25 PM OK Don wrote: > It depends on how long you expect him to keep the car. If it will be > replaced in a year or two, use the thread fixing epoxy, if longer,

It depends on how long you expect him to keep the car. If it will be replaced in a year or two, use the thread fixing epoxy, if longer, do it right with a helicoil. On Sun, Oct 25, 2020 at 6:02 PM Kaleb Striplin via Mercedes < mercedes@okiebenz.com> wrote: > My biggest concern with that is

Axle grease in the drill flutes and in the thread tap catches the shavings. I've never had an issue with shavings remaining if I do that. Work slowly! Allan Kaleb Striplin via Mercedes writes: > The hike opens up into the timing chain cavity. There would be a worry about > getting metal

The hike opens up into the timing chain cavity. There would be a worry about getting metal chips falling down into the engine. Sent from my iPhone > On Oct 25, 2020, at 9:35 PM, G Mann via Mercedes > wrote: > > You have the threaded bolt that fits the hole. Use it to determine the > thread

You have the threaded bolt that fits the hole. Use it to determine the thread count and pitch.. Perfect match. That should be a blind bottom hole. Use the Helicoil taps that will come with the kit for that hole size and thread match. Use wheel bearing grease to fill the lands of the tap. that

My biggest concern with that is getting the hole drilled straight.  Probably would need to remove the radiator to have more room to work. On 10/25/2020 5:48 PM, OK Don via Mercedes wrote: Having done all of the above, I would helicoil it. On Sun, Oct 25, 2020 at 5:43 PM Kaleb Striplin via

I do not think I am going to helicoil it.  I see the potential to make it much worse.  I see several folks on the forums mentioning they just coated the threads with JB Weld and it has been fine. I also have seen this Locktite thread repair and thought about trying it.  Basically you coat the

My next concern would be cleaning up the shavings after tapping and installing the helicoil. I have first hand experience with this from helicoiling a head hold down stud in a VW case once - despite out best efforts at containing and then removing the chips, the engine seized in about a mile or

Working on my fathers 98 e300 doing routine maintenance. Noticed the belt tensioner was cockeyed. Typical. On this car the tensioner was loose with the PO and he I believe used some lock tight and tightened it back down. The threads were somewhat stripped out. I was aware at some point it could
