Maint work on my lanos - *Upd* pics of turbo and oil feed

Post by ubuyau »

Over the past 6-8 weeks ive had a bit of maintenance work to get done on the lanos and thought id post pics of some of the parts that were changed. Most of the work was done by shops, but i was full briefed on everything which was cool.

Stuff changed in seperate occassions:
- Clutch, slave cylinder, the fork the slave cylinder pushes on, throwout bearing and brake fluid bleed and change (we did the slave cylinder, shop everything else)
- Water pump (shop)
- Spark Plug leads died (we changed these too :oops: )
and most recently
- Cam box, timing belt cover and belts replaced again, full head rebuild with light smoothing, new head bolts, all gaskets including new headgasket and some hoses replaced (all shoped out).

New Water pump, hose and o-ring

Returned parts from the various jobs - check out the crack/broken piece from the cambox! Yes oil was spewing everywhere - managed to get the car home and to the shop alright though!

Broken Cam box, Slave cylinder, throwout bearing, water pump (yes it was well worn) and clutch arm.

Got the car back today and it now goes like a dream... better than new and i only drove it a few kilometers from the shop.

Does anybody know how the cam box would crack like that? It looked like a bit of a dodgy casting. I may have hit it with some water when the engine was a little hot - would this cause it?

Also, does anyone know on the 1.5 SOHC, if you can change the thermostat without pulling all the timing belts off again? It looks like i have been given a new one but the old one is still in the head and it wasnt replaced. Just want to know the amount of work.

how much kms did you have on that old water pump?? it seems in a good condition to me to be replaced. the reason i am asking is that i intend to replace mine at 80,000kms.

as for the craked cam block; no idea man, it is the first time to see that happen... did you have any work on the cam block or cam shaft before? maybe this was caused by bad reinstallation or using force during installation but i am not sure.

i was told by woo_sleeper that you can remove the thermostat housing without removing the timing belt... i tried it myself and found out it is a very hard job to do but still it is doable... the real question is: will the space created by removing the housing allow the thermostat to come out??

i have no answer on that one as i was hunting for a housing removal to cure a coolant leak their so i never tried to remove the thermostat... I?d say removing the belts is better than spending time trying to get the thermostat with the belt on... the job is not that easy and the frustration will be colossal if you did it that way and couldn't maneuver the thermostat out.

Water pump had 118 000 kms on it. The seals were leaking and it didnt spin smoothly. It was a good replacement.

The cam box we still have no idea.

Shop says they can change it without removing the belts. Should be getting it done soon.

Well an update on this is that the joy was short lived. I found an oil leak (that wasnt there before :cry:) Anyway, ended up finding that it was coming from the oil filter sandwich plate and the christmas tree oil feed arrangement for the turbo. When they had taken it off, they had torn and crimped the Viton oring seal between the plate and the block (so i had to spend another $12AU on a new viton oring - BS230 oring) and they hadnt sealed the hoses properly. So this meant i spent all day yesterday fixing stuff which means i finally got to take photos of the oil feed arrangement (finally) and some more of the turbo. :)

Turbo from bottom - Oil return hose is 1/2 inch stainless steel braided then lagged in heat wrap for extra protection. Yes it flows a little uphill but runs perfectly.

Sandwich plate with christmas tree - 1/4 inch stainless steel braided hose - all sealed (extremely important!)

Refitted to the car (Notice the aluminium speedflow arrangement for the oil return - the blue nut and red elbow Speedflow fitting was screwed onto the weld on Speedflow adaptor).

Its to get a feed of oil for the turbo. Also makes running an oil cooler later on a bit easier (I havent found it necessary yet). On the bottom of the christmas tree, the long feed hose wraps round the back of the exhaust manifold then onto the turbo.

Its an alternative to removing the oil sensor at the back of the block for your turbo oil feed. I think you dont get quite as much pressure thru the sandwich plate (but still plenty for the turbo - you can dump the whole 3.75 Litres of oil past the oil filter/sandwich adaptor in about 5 seconds (yes i found out the hard way - twice) :oops: ).
