Updates.
Extra van only moved once last year and has been laid up ever since. To recap it needed a bit of work doing, inlet gasket was leaking on cyl 1 causing a bit of noise on boost and a fuelly mix coating the inlet, and down on power but not by much. I had the parts in stock, but lacking motivation id failed to do anything. Not a massive amount of work, inlet, exhaust and turbo off, but if you cant be arsed its easier said than done.
I have Croft booked for Easter Friday and its looking likely the r26 will be in the bodyshop, so with 8 weeks to go ill see if i can get this ready.
Made a start.
45 mins later, inlet off and turbo moved out of the way.
1hr30 in, fully stripped. Its fiddly to work on but easy in some respects as its all done from the top.
On stripping the gasket off, noted cylinder 1 & 4 inlet ports had split the gasket and rippled the stainless side. All bolts were tight so it had not blown out due to lack of torque on the fixings. Never seen a c1j gasket fail like this, i assume its high egt, high emap (exhaust pressure) related and the cast manifold moves a bit.
Oem renault gasket not up to the job.
Interesting ripples on the stainless side due to movement, cracks visible.
Ive had these fail before but not like this. The new one has stainless plate both sides and supposed to be better. However might be time for a material change, i have a lead on a copper gasket.
Id noted the starter wiring was a bit tired last time id been underneath, heat had affected it and the plastic conduit was melted. The r5gtt runs a starter motor heatshield originally but they fall to bits and get binned, ive done thousands of miles in this without issues but the efi engine is a different animal and clearly needs some protection
With access good the heat damage was clearly visible, Not the best.
Touched it and everything fell to bits revealing 50mm or so of bare live wire. This has no fuse as standard, good job it never touched anything or could have been sketchy.
Heatshrink would not go over the angled connector to the starter + terminal so only option would be tape which is a bit bodgy. I need the angled connector and opted to splice a piece of new wire in. A quick rake about in the spare wiring and a bit of megane starter wiring found. Needed the angled connector for starter as access is tight, so crimped a straight joiner in, and chopped loom back which revealed an oem joint.
Hydraulic crimper gives solid joins.
Dual wall heatshrink x 2 layers.
Original loom cut and joined at oem joiner.
Dual wall heatshrink.
Fibreglass firesleeve added for heat protection.
Starter motor had seen a lot of heat. Ideally it needs a heatshield making but can wait to another day. Added some dei reflective tape i had spare.
Refitted. Added a heatproof ht lead cover over the firesleeve, should be adequate. Ill add a maxi fuse into the positive wire to batt to avoid any issues in the future.
With this done started cleaning up inlet. The fuel vapour is clearly visible with added bit of exhaust blow.
Quick once over with brake cleaner.
Ran out of time so will refit today.
