  • Project Corona

    So it’s been a while since i have needed to do much related to the engine of the S2, mainly because it was completely rebuilt by DJones A few years back following a particularly fun ADI, where i toasted the bottom end driving round on track rubber all day.

    Everything has been leak-free ever since bar a power-steering pump failure and leak Of the stinky, sticky G00. However age rather than miles means time for a cambelt change and an opportunity to have a decent poke about...

    On the list of jobs following a good look over:
    replacement of the coolant pipework
    replacement of the breather pipes
    removal of redundant a/c pipework to ease access around rear of the engine and behind drivers-side front wing
    replace the rear diff oil seals

    The small bore rubber hose connecting to the metal line that runs around the front of the head was shot, as i remove the clips it was split, so count myself lucky it hasn't let go earlier And stranded me or toasted the engine!

    A good poke about revealed that the breather hoses were well past their best and in particular the t shaped rubber hose hidden behind the head which always goes mushy. To be fair this was one of the first things i bought and replaced on the car since i owned it from July 2000 so its done ok

    Having removed the radiator, some of the coolant hoses were looking like they were also past their best and some of the zinc plated jubilee clips had left their corrosion all over the hose too, so started to rip these out and ordered fresh replacements from Roose for them and the breathers.

      With all the intake plumbing removed, checked and cleaned ready for reassemble with new clips and vac hose, time for a nose about the exhaust side of the bay. One consistent weak-point on the coolant circuit is the rigid line from the underside of the k24 back to the nipple on the head which has a small length of rubber hose on the end.

      The heat cycles take their toll here and the jubilee clip was toast and a small weep was evident...this is the 2nd or 3rd time i have found this...i will replace this with a hnss clip to hopefully better deal with the harsh conditions under the manifold. Also appeared that some of the washers used on the braided oil return lines need to be replaced too as they are being attacked with corrosion...so much for oem quality

        Be careful... A friend started using his lockdown time to deal with a leaky o ring in his water manifold... Last week I leant him my engine crane and now his engine is out and on a stand!

                easy done right i am thinking about whether to change the clutch at the moment while it just fuel lines connected. Also need to wait best part of 4 weeks for the Roose hoses it seems.

                    Looks like you’ve been busy. Just dropped mine off at my garage going for a thorough check on everything to make sure all is good.

                      ...and here we are. Waiting to grab a hoist to get the engine out and do the clutch, two new wings ordered, new slam panels to come then, after 20years of ownership, she is going to be painted and hopefully returned to her original, pearlmutweiss glory. Still havent finished the timing belt change due to my back but some gentle spannering can now recommence

                        Nice one. Get a friend to tighten the cam bolt for you. It not a good idea for you to try with your back!

                              Bit of dismantling today, cleaning out the gunk of g002000 which was all over the nearside and gritty. Nasty stuff at the best of times. Fair bit of surface rust and paint flake...
