Engine its OMG

Recommended Posts

Hi to all you Esprit fans im in need of your help.

ok heres my story, i have become the owner of my childhood dream car, my best mates dad was the owner of the turbo esprit 82 dry sump. For many years i pested him to let me take it out for a spin, at that time i was a young cocky 19 year old so the answer was always "not a chance".

About 15 years ago he had an over boost problem and pop went the engine, having rebuilt the engine again along with the turbo he sadly had it over boost again!!!!at this point he parked it up in the drive and intended putting the rover V8 conversion in it.

about 5 years later his son (my mate) came home from the states and decided to pull the engine out to fit the rover conversion, thankfully the 2 week visit home from the States was only enough to take the engine out and strip it to bits!!! (completely)

Ok, after many a few beers, lots of nagging, pestering, and arm bending he (mates dad) called me up to talk about the car. and yes i became the proud owner of it.

So here i am with a lovely car that I considered chopping about to put another motor in. Now before you all crucify me ive already had a chat with PNM who has very blunty told me what he thought of the idea and steered me back on track. Now comfortable with a spanner in my hand as a schoolboy petrol head where do i start? Its one thing to strip and rebuild an engine but this one is already stripped to the last nut/stud/bolt and washer. Heres what i know. Having stripped the turbo ive found some debris of not just the last pop but the one before!!! Also the wastegate was locked solid? Was that due to standing up the last 10 years or the cause of the over boost?

Right what have i got, I have a spare gearbox, spare turbo, spare wastegate, another head, stainless exhaust, a few spare valves, pistons and liners and many more. I am planning to send the block pistons and liners to PNM engineering (great guy over there realy like his passion even though he gave me a polite bollocking) for inspection balancing and bonding liners in. Sieving through the parts yesterday i found myself thinking i should get a better picture of what I have and want before i start spending the pounds.

your thoughts, help and advice will be greatly received.

Hello Tod!

 

Im in Norwich and done the almost same thing. Glad as hell you didnt replace with a [email protected]£king low powered rover V8! Honestly the number of V8 conversion that are started but not finished are frightening. You have a lot of work before you but lucky for you the factory is close by and many people here will be able to give you help and encouragement!

 

Here is my rebuild if it may help and the condensed vid is below!

Head over to the introducing section and say hi, but there are a few Esprits here in Norwich and a at least 4 G cars. So that will be handy if you need a peek at something when you come to refitting.

 

Best of luck feel free to ask any questions and we love pictures here.

 

Buddsy  :thumbsup:

Welcome to TLF Tod. :welcome:

 

Best of luck with the engine rebuild and stuff.

 

As Buddsy said, head over to Introductions and say hi. :)

Hi Tod, welcome to the fold, and with the best year as well :thumbsup:

 

My wastegate was stuck - giving overboost, so blowing the rings when it was driven by a "specialist" garage.

 

Any pictures?

Overboost is a common disaster for these engines. Fine if you keep an eye on the boost gauge, spot the condition straight away and avoid overboosting ... and get it fixed asap. Usual causes are the valve on the wastegate seizing up through lack of use...or the diaphragm getting holed. Diaphragms are about £80, I think...and the valve problem is solved by dismantling, cleaning and reassembling...I use synthetic oil on the valve stem and guide and that seems to last and work well. You're going to need a copy of the "Service Notes" and Parts List...the parts list is available online here if you are a full member, and software copies of both are very useful, in addition to the stone age paper ones. There's nothing in a 910 engine that can't be done by a talented amateur...and your talent will grow as you go through the task! Bonding in liners isn't a huge task...like everything it has to be tackled logically, slowly and carefully with lots of thought. Take your time over the rebuild and check everything at least twice! I find that working on the Esprit is a satifying task as the end result is magnificent and stands out from the herd....far more worth doing than grovelling under something that's simply transport!!

The best I found for cleaning up the aluminum castings was Meguir's Alloy wheel cleaner and stiff wire brushes in a big drill or small hand ones in smaller areas. I then painted with Por15 Aluminium engine enamel from Forsts.

You dont have too paint I just liked it but Frost is a good site to buy tools and paint.

Tod you need to find a hot tank or a ultrasonic cleaner to get the parts clean. I know of a hot tank down in Essex they use for just this purpose if you can't find one locally.

Although you may think Gunter's post was done in jest--and I'll admit nothing beats a hot tank or ultrasonic cleaner--the "super hot water/scrub brush/cleaning pads" route can work wonders. And yes, you can actually use dish soap after your first thorough degreasing--and perhaps cover your parts with a layer of a non-pumice based cream hand cleaner, then scrub them off. I've added sugar to my hand cleaners instead of pumice (fearing scratching the surfaces).

 

I just spent the summer cleaning up some aluminum parts (billet pulleys) and a cast Eaton M62 supercharger prior to its rebuilding.  When I disassembled my supercharger, I bought a plastic storage tub, poured "Purple Power" brand degreaser into the storage tub, then plopped it in and let it soak. Be aware many degreasers warn "not for use on aluminum". That, along with orange (citrus) based cream cleaners and green 3M pads, combined with thorough rinsing by volumes of water, worked wonders.

 

I used this technique to clean large layers of oil (from the PCV system drawn into the supercharger's interior) as well as baked-on exhaust residue (from the Exhaust Gas Recirculation, or EGR, system). 

 

Furthermore, I also used the same "Purple Power" and citrus-based degreasers (alternating the two) to soak the intercooler and the aftercooler. You may notice, as I did, that if you tap some parts after degreasing and allowing the part to dry, bits of gunk flake off like tiny pieces of dandruff. My intercooler was so full of crud I soaked/dried/tapped very lightly, then soaked it again.

 

I also used "CLR" ("Calcium/Lime/Rust") flushed through both cooler units. This yielded little (as my coolant wasn't corroding the interior of the aluminum coolers) but some stuff did come out of the interior. 

 

Cheers,

 

Scott

I totally mean it serious  ..those who have seen my rebuild now what I mean - DIY with household chemistry can work wonders if you know how the physics (chemistry) behind it works.  Alkaline products with higher concentration, like toilet- or poolcleaner are perfect for slightly oily alloy parts of the block

 

..and for rusted steel parts done from mild steel:

simple degrease it in petrol/aceton ..and after that put it in a bath of citric accid, this is the fastest way to get rid of rust without mechanical work or a wire brush

 

-you will of course loose much of the remained plating  

 

..and keep zinc-cast parts out of contact to citric accid, as it "eats" it up !!

Best way to attach pics is to set up a photobucket account. You can then add as many pics as you want. There is a how to here.

Simon350s cleaned his engine parts in the dishwasher. It does degrease them but dont invite me round for dinner!

You in your black one, "Ilovecoocopops" in his Essex blue 84 one, "Clemo" in his Ice Blue 86? one and me in my Red 85 one...we could cause havoc round the coast or through Norwich in the summer! Thats a lot of G cars around here now!

I'm was going to just re build the engine drop it in and use the car for a while to show the other potential problems, Having read through some of these forum rebuild posts i'm begginning to re think and and a few jobs to the list while im at it. so count me out til at least late spring. Although im keen to come look at some examples as i have no idea how it should look when i put things back together,

 

Planning on over working the dishwasher this weekend cleaning engine parts. Wish me luck, lol the missus may need to add a new dishwasher to her Christmas list after i've done.


I have a spare set of carbs as well i believe, is there any way of checking/bench testing which set is best to use?

If the car has been stored in a good place and was looked after before it came off the road you may be best to only do what is needed right now. Once on the road you will be able to do any other running part as needed such as wheel bearings etc. The trouble is with a long rebuild it is very easy to loose the motivation with the time and cost and not much enjoyment. If find you need to pull the engine again in a couple of years well so be it but you should be able to do most of what you need first time round.

 

Clemo come on more positive thoughts old boy!  :ice:

I'm positive that as both cars stand, neither mine nor Simon's can move under their own power, irrespective of legality, they jusy cannot run.
