Do these shims go inside the followers, or is there a recess in the top and they contact the cam? Rick

There is a recess at the top and they contact the cam. You can replace them with the camshaft in place but you need a special tool.

They are case hardened which is a shame because otherwise a homemade solution would be sufficient.

I haven’t called any of the motorfactors yet but they are slim pickings on the net. Nissan want about £28 a shim which is ridiculous. A guy in Australia can get them for $3.50AUD which is about £2.00 ex postage. Probably order them from him and they should arrive next week.

Shims found at Lymm Engine Parts for £3 each. The selection I need is on its way.

Nice find:thumb2

A good find indeed, Rick

 

[Flying Torquewrench]

Only a small update for today as I am waiting for the parts to arrive.

I have cleaned the inlet manifold and chased all the nuts and bolts with a tap & die. Of the parts that no longer come apart I have changed the seals and now it is all ready to go back together.

Valve clearance shims should be here tomorrow, so hopefully I can get most of the engine back together over the weekend.

The shop that overhauls my injectors has found the correct parts and the injectors should be with me next week. As I am at work at the beginning of the week so it will be a job for Thursday.

In the end I decided against replacing my injectors with a new set. A new set would have been £600 more then having them repaired but it comes with a 8 week delivery time. I might still consider to change them all over and keep the reconditioned set as a spare set but I first want to get her up and running and then take it from there.

 

[Flying Torquewrench]

Typical, while today should have been a cool and dry day it has rained instead. I had planned to get the engine back together in preparation for the injectors. That didn’t happen so instead I build up the head.

The pipe that sticks out of the head is for the coolant. It just screws into the head without any seals/washers so might just put a bit of PTF tape on the threads to prevent leakage.

Replacement shims.

 

[Flying Torquewrench]

The right tappet has the shim removed and the left tappet has the shims still in place.

 

[Flying Torquewrench]

With the new shims installed the clearances on the valves were all within limits. As it is a new head I will recheck the valve clearance in a few months time.

Also installed the new glow plugs with lots of copper grease and hand tight. Once the valve clearances are checked I will also give the glow plugs a new coat of copper grease. After that I will recheck them every 6 months. Might be an overkill but in the end it saves another new head.

Before calling it a day today I installed the injector tip protectors. They came with the head but were in a separate bag.

Your head is so different to mine, wonder what the benefit was for the change? Rick

 

[Flying Torquewrench]

The RD28ETi engine, intercooled and electronically controlled also has different pistons then the RD28T. It has a slightly higher BHP 133 vs 123, unless it is the RD28ETi2 which has 143 BHP. And it has the max torque and BHP at slightly lower revs.

Looks like they redesigned most of the engine when they changed it to an electronically controlled one.

Waiting for the sealant to dry so I have a bit of time to post some pictures.

The underside of the head.

Head gasket is on.

And finally, the head is in place and the bolts all torqued up.

Hoping to get the Turbo, inlet/exhaust manifold on today and with a bit of luck get the timing belt back on.

 

[Flying Torquewrench]

This is how I had hoped to finish the day. Rocker cover back on and ready for the timing belt.

The photo shows how far I got.

 

[Flying Torquewrench]

Unfortunately then I realised that I should have tightened the camshaft sprocket with the rocker cover off. Hence why it all had to come off again. :doh

Also between the black plate (behind camshaft sprocket) and the cylinder head there is a seal. This needs to fit into quite a small area and this is a right pain in the arse to get right. Below is how the seal sits after I fitted it the first time.

Spend around and hour to get it right and failed miserably. In the end I removed the seal as its only job is to stop crap getting into the timing belt area. With the seal removed I just need to keep a close eye on the timing belt an potentially change it a bit earlier then recommended.

 

[Flying Torquewrench]

The projects is on hold for the next few days. I had hoped to get most of it done yesterday but it has been raining the whole day. The next few days I am on standby for work so can’t do anything as the call to go to work can come at any moment. Thursday is my next day off and it looks like we will have half decent weather.

New turbo on Ebay for the Y61 https://www.ebay.co.uk/itm/363446021885?hash=item549f122efd:g:2MIAAOSwXx5ghxTb#vi-ilComp Rick

£124 is extremely cheap for a brand new turbo! I would be very hesitant to buy it at that price as it is only 1/4 of the normal price.

It's a cheapie cheapie!!!! At that price I'm tempted to just buy it and stick it on the shelf as a spare :duno:
