Hi All,

Just had my new oil pump delivered, ACL bearings due in tomorrow.So will be

starting in the next few days to start the process of replacing my crank , bearings and oil pump.

Any advise on carrying out this work will be much appreciated.My brother-in-law (mechanic) will assist as and when I need him but will be trying to do most of the donkey work myself as he's very busy.I will be letting him replace

cambelt etc !!!!!!.

Please can any one advise other stuff I may need to complete work I need to

do the job gaskets/etc/etc.

Generally any info/help whatsoever please.

 

Thanks:helpsmilie:

Alot of people would suggest to do all the gaskets while you are at it and you would be best getting a gasket kit like this

Ive currently got my spare engine in pieces to rebuild and will be using most of the gaskets in the kit. Also look at threads on EGR delete and Plenum water bypass might as well as the engine is out. CZP can supply the parts alot cheaper than you can get in the UK and with the postage as well. Also i have had parts from them before and not had any import tax to pay just email them with what you need and they can source it for you.

Hi Mate,

Only doing bottom end and hoping to leave engine in place.Only want to

spend on gaskets neccessary for replacing crankshaft etc as after buying

crank / bearings / oil pump + customs charges/ cambelt really adding up.

Like I say your help is really appreciated and any info of anyone is grateful.

 

Thanks John.

I take it that you are removing the engine? Still would be worth to do an EGR bypass and plenum water bypass very cheap to do too. Have you also got both the crank seals and the bushing as well?

Hi'

Hoping to leave engine in if possible. No I havn't got the crank seals yet,that was going to be my next question (where to purchase at best price ?) Do you know approx price ? Could you tell me about the "bushing" + details cost /etc,

sorry I'm not a mechanic so not clued up as I'd like to be.

Originally bought an engine off djpeterj off here and was just going to replace

engine but got hold of a crank then decided to go that route.Think I should have stuck to original idea but just going to plod on now.

What ever else you think I'll need please let me know (magic wand would be nice).

Just glad the brother -in -law will be over seeing all work (just its going to slow it down due to his availability)

 

Please keep any info coming

speak to MR F on here about the parts you require like the seals he can get very good prices from nissan and should only cost about £30 for the bush and 2 seals. Also might be worth asking about a sump gasket but i would say it will be quite a difficult job with the engine in

Which bearings are you replacing mate.?

Big end only or mains as well?

Was you intending to replace the crank?

Hi mate.

I've now e-mailed Mr.F cheers.Appreciate your help.Believe me I'm under no illusion it may turn out to be a bas***d of a job insitu.:sad:

Hi mate,

Replacing crank , mains and big ends

you will find its an almost impossibe job , the cross member hass to be dropped to remove the sump and as the engine mounts onto it you will have to support the engine which means taking out coilpacks etc and hoses.

 

the gearbox will also have to come off obviously along with starter etc and exhaust.

 

i would say it would actually be quicker to take the engine out.

 

my main advice would be that if you had a big end failure then there will lots of bits in the engine so it will need to be really clean to prevent this happening again. ie put through an engine wash.

 

i had a similar issue with an s14 i owned. the previous owner had done as you planned but it was not long untill the problem re occured.

 

only my 2 pence worth though.

 

More than willing to give advice though

just realised you are in shropshire.

 

where abouts. im sure i can pop over and lend a hand if that helps

damn it, engine out job, would of love to come and lend a hand too. but i gotta wait till cars taxed, and not smoking before i venture anywhere. :(

Hi mate.

You got me worried so I rang my brother-in-law. Thankfully he said I could still be using car as it hasn't had a total bottom end failure but my being over cautious and not running is best as it avoids as you said (bits getting into engine).

Thankfully he also assured me with my help he will be able to carry out work

without removing engine. He did add " it won't be easy !" but he doesn't seem phased at all ,so thats good enough for me. (I daren't offend him he's my brother-in-law "nothing to do with the money he's saved me over the years and hope he will in the future of course:wink:"

Can't tell you how much your offer of a hand means, as usual fantastic forum

members. Just hope you understand I don't want to offend him being family &

always helping me with spot on results.

Will let you know how it all unfolds as and when I get started.Hope I don't give you reason to say "told you so".

Thanks for everything mate.

 

Located nr Whitchurch.

no problems mate,

 

let me know if you need a hand or get stuck for parts on a sunday etc

Cheers buddy

All the very best to you. Will keep you informed.

Red, just a question but whats happened? you say it hasn't suffered total bottom end failure, yet been advised that its safe to drive? are you experiencing any knocking at around 2500rpm? because if you are, id say the best option would be to leave it till the work is done.

 

This is the lower part of my piston after i blew the engine.

 

if the mains and crank need doing mate. you really should think of doing this job engine out. as you will need a total clean of the engine and there may be other damage.

In my experience if the mains are gone then theres been somthing bad gone wrong in there. the z engine is almost bullet prof so rare to see mains blown.

are you sure its not just big ends you need?

Hi

Feeling is that it probably is just big ends starting. When I said ok to drive (only meant if absolutely necessary for emergency etc as would obviously not help by continuing to use). I'm probably being over critical and could have just done big ends, but dropped on a crank ,so decided to replace along with mains/big ends and oil pump while doing job + cambelt.

Could have put the engine in I bought from djpeterj but this engine seems sweet and very strong apart from big ends so I thought it was worth the crank,new oil pump etc and then try to recoup some money with other engine.

Hope I've made right decision .

Appreciate all feedback and offers of help from you all,thanks again.

That was when I put two conrods through the oil pan lol, if I can find the other photos I'll show you how bad it can be, bare in mind, mine blew while driving, and managed to crack the cylinder block in two places, snap two conrods, one of which punched a hole in the oil pan the other smashed it's way through the block, the counter weights mangled what was left.

 

Not trying to scare you or anything but if your big ends are failing best just to not drive it at all, will lessen the damage you have to fix

I bet you a sack of potatoes you either destroy it trying to do the work this way, or end up having to take the engine out.

 

You need to start listening to people on here... they are all zed owners and have done stuff like this before. Working on these cars are very difficult and its simpler just to take it out.

Hi mate,

Yep the photos are scary alright,don't worry the car hasn't been used, its been tucked away in the garage for quite a bit now awaiting the work. I knew it wasn't worth using it. Looking at the photo mate and your comments,it must have been a really bad time for you when it went bang.

As you probably know I've always had a Z for over 10 years and been a member for 6 now and know they can be difficult to work on.Which has taught me you guys definately know your stuff and you've all helped me endlessly over the years (not only with the Z's) .

When I get down to it will keep you informed on route taken.All the best.

(You never know ,I might have to buy a bag of spuds to add to the pain)

Good luck with it!

Gutted wasn't the word, but it did have a light at the end of the tunnel, I'd say the best option for you would the engine swap, it really isn't that bad as I managed on my own with only a bit of help with the spigot bearing from jamieTT, I'd much rather do a engine swap than try to rebuild the bottom half of one with the engine still in the car.

Good luck with it!

 

Cheers,looks like I'll need it.

To be honest mate,I wish I'd bit the bullet and got Jeff & Jamie to do the work.

I did some panic buying "engine from djpeterj" then decided to go other route so ACL bearings, crank ,oil pump from USA, seals,thinking I may be able to recover some costs by selling the engine on, but me being a knob have maxed out financially with purchases (soon adds up).

At the end of the day labour costs scare the s**t out of me and it was the only way I could think to keep my costs down. (After the amount of grief I'm putting myself through and head scratching decision making what bit of hair I have left, will be gone).

Same old saying mate "You make your bed,You lie on it" but mines mighty uncomfortable at the moment and not giving me much sleep.

 

Sure it will all come good , I hope. Thanks for advise mate.
