[@razenby]

Glad you enjoyed it

[@user-ps2fg6ym3q]

Very well done. I watched other videos this was the best.

Glad you enjoyed it! The tensioner bearings wear out quickly on this engine. It must be because they are in the weather.

Very common for the bottom pulley to ingratiate water and spay across belt. Then drip into pulley springs for auxiliary units we used to clear drip tray. Hmmm #### Shelia as in trade. Also I remember the belt clack ? Like a duck sound was slapping of belt on and off. Horrible garden sheds they are, have you had the break bias problem yet ? Snappy rear end good luck with that

Thanks Brian. The car has don about 70K so it is just exhibiting a few minor problems. All the brakes and disks were replaced before we got it. That rear will punish you if you exhibit the dexterity of a safe cracker on the throttle in the wet.

Haha, it is the thing that you use to remove the nurdle clip from the grungling wheel but only on a Wednesday.
