    Remington Firearms

    Hi Anyone have any knowledge as to what will happen to Remington Firearms? The other parts of the business have been sold off to the likes of Ruger and Sierra but what will become of Remington? I am hoping the new owner will restore the 700 to the quality it once was.

    Hi As anyone who has read my posts will have realised, my knowledge of all things on BITOG is in its infancy, but I am learning. Could anyone tell me the difference between mb229.5 and 229.51? Is the latter just an evolution of the former? I am thinking 229.51 evolved to 229.52. Many thanks...

    OM642 Oil change procedure

    Hi lads I have read on many forums and seen a few 'you tube' vids stating that when filling the OM642 Engine, half the oil must go in via the filter housing. Some say this primes the oil pump, others say it lubes the big end bearings. Is this an urban myth that has 'grown legs' by being...

    Hi Gents. Which Coolant to use for a Merc' OM642 3.0crd in a 2008 Jeep Grand Cherokee? Should I use a G05 HOAT as suggested by Jeep or a G05 as suggested by Mercedes? Does it indeed matter? At the moment my coolant is orange if that is of any relevance at all. Many thanks. Tikka.
