Anyone had a block sleeved?


Recommended Posts

Hi shiters


I've hit a problem with my 2.0 pez turbo XM after reassembly of the engine with a good skimmed head. Rough idle and EML on led me to do a compression check and the results were depressing; 3 cylinders in the high 90s psi but one at 62 psi. So cylinder one is looking borked but normal oversize pistons are not available, just Germanic forged racing jobs at £500 plus. So I'm thinking about having the cylinders bored and sleeved back to standard. Anybody had any experience of this both cost wise and durability wise?

My 944S dropped a piston ring, scoring the bore.

The other three were still within tolerance even at nearly 300,000 miles so rather than re-bore the whole block, just the one was bored & sleeved.

From memory it was about £130 or £170 - a mere fraction of the cost of all the work that was done.


The engine is running like it's brand new but it's probably only done about 7/8,000 since the work so I can't comment on longevity yet.

Thorough check of all the top end components before you condemn the bottom end.


I remember a guy on youtube showing how easy it was to get the liners out of a RV8 - heat up in oven then push out.

I'm fairly confident that the OP has checked the top end as being good...

Try these guys, if they don't have your piston(& rings) they will make it for you.




Prices are very reasonable, i paid 300€ for a set of 4 sleeves, pistons and rings for my 504 GL not so long ago.

I thought the rule of thumb ok figure for a compression test on a petrol engine was 100psi or better and most modernish engines seem to give 125psi or thereabouts. I suppose 'high 90s' is almost there, but would hesitate to spend too much fixing the low reading bore if the others were well past their best.

No, No NO! Clearly the answer is to use the magic gloop that Quentin Wilson endorses in the back of the clasic car mages that makes your 500k engine just like new because it contains PARTICLES and as everyone knows that adding magic particles will restore compression to better than new.

They're still (well the dished ones) on the Mahle catalogue. RGX or RGY?


circa 60 quid a pot.

I've checked the Mahle catalogue and they are indeed listed. Question is are they available? XU10J2TE was a popular turbo conversion for the 205 gti crowd and all their forums suggest pistons are unavailable. I will follow this up.

      Having recently had some tussles with a dead BMW ECU, I thought this was really interesting:
      Especially how the guy managed to update to a newer version of Ford Sync enabling CarPlay.
      I am tempted to really learn this side of 'shiteing' as well as mechanics.

      Welcome one and all to the new home of average transport.
      Most of the forum will work exactly how you expect it to, but there's a few differences which will hopefully make your life easier. We'll add to this first post as other things become apparent or we find new options, seriously it's like getting out of a Fiesta Bonus and into a Sierra Ghia with all these new buttons.
      Reading posts
      You can hover over a thread title to see a pop-up and choose either first post, or latest post to quickly preview it without clicking into it As before, you can click the star or circle to the left of a thread title (star is if you've participated, circle for threads you've only read) to go straight to the unread post  
      Composing posts
      If you want to only quote a few words from someone else's post, just highlight the words with your cursor in their post and you'll get a "Quote" popup rather than having to quote the whole lot and delete the extra test (Thanks Stanky!) Tags and Prefixes are somewhat different to the old version! A "Prefix" is what appears at the start of the topic title on the forum, and tags appear at the end You start by entering one or more tags. Seperate them by just pressing enter to finish that tag and start a new one. You can then optionally choose one of them to be the prefix by selecting it in the drop-down Default behaviour seems to be that it will automatically select the first tag as  the prefix, so it appears twice. Looks crap but it's a "feature" for now. Deselect it if you want....  
      Image linking and embedding
      You now don't need [ img ] tags around pictures from elsewhere on the web. Simply paste an address that ends in .jpg or .png etc and it will automatically embed it If the image address doesn't end in .jpg or .png try clicking the "Insert other media" button below the text entry field and paste the address in there. When using the file uploader to embed your own photos from your computer, you can just drag them onto the bar below the text entry area. Once you've done that you can click the plus icon on the photo to embed it anywhere in the post (put your cursor where you want it to go first) If you've already used an image somewhere, it doesn't need to be reuploaded. Click "insert other media" and choose "existing attachment" to browse all the images you've ever uploaded. If you don't want the image embedded inline, you can press ctrl-Z to undo (or use the link that appears at the bottom of the compose window saying "use link instead" for a few seconds after it embeds) and it will go back to the old behaviour with just the address of the image  
      To find your own content, instead of “My Content” you can use “Search My Activity” which is at the top right of the forum. It’s sort of notifications and all sorts rolled into one but there’s Posts and Topics as sections in the left hand menu Tags and prefixes are clickable to search for other similar content. If you click on Activity on the main menu, there's a detailed search for your own content, member lists (separate tab) etc.  
      Signatures, Display Name, Email address
      Click your username at the top right corner, and select "Account Settings" Edit your signature, display name or email address there. You can also turn off seeing other people's signatures Note signatures don't display on mobile devices to avoid taking up too much room  
      The "like" button is gone, and Reactions are here instead. You've got like, thanks, sad and confused.  No, you can't like your own posts  
      The forum seems to default to "Follow topics I reply to" which is the same as Old Autoshite, however.... The default behaviour is also to email you notifications. Oh no! That's a lot of emails..... Click the Notification Bell at the top right, and choose Notification settings. The four options for notification frequency let you summarise things into one email. The top option doesn't specifically say "emails" as the type of notification can be controlled in the next step. Scroll down and you can toggle emails or notifications for each of the different events (like someone replying to a topic you've followed etc).  You can also turn the notification sound off in that screen if you're thinking of perving over Austin Allegro Equipes (yeah, that picture) at 3am in bed.

      Hi all,
      Apologies for the downtime, there was some routing issues with our hosting provider which meant the server was cut off from the outside world. I'm finding out what went wrong and how we can avoid a repeat.

      A proper shite 90s jet ski just came up by me and I’m sorely tempted. Looks like a decent version of the year, a seadoo spi.
      Seems rotax powered which I remember from my karting days and I’m hoping to go and see it tomorrow. Looks like a two cylinder carb fed job.

      Anyone played with them?
      As usual the engines in bits and it’s missing the jet whatever that is. Presume where the prop fires water down?
      Are there any rules to it’s use or can I just get it running and blast about on it on the local water and lochs?

      So I’ve held off here for a month now but I’m stuck and need advice.
      Some of you might remember I had a Golf Turbo estate for sale in Jan. Well I sold it to Exiled_Tat_Gatherer and he paid for it with the intention of collection.
      But, I haven’t had a message off him in nearly 4 weeks now and I’ve messaged loads. I’ve phoned him and got voicemail. Now I’m not trying to muddy the lads credibility at all, he’s done his bit but I’m worried about not being able to get in touch.
      He’s in Belgium and intended to fly over and collect. I’m aware he bought numerous other cars off here and wanted to collect them all in a oner but he’s now not posted in ages.
      What the hell do I do? I really need the car shifting but he’s paid for it. I can’t store it forever and I’m still paying tax on it so it can be legal for him to collect.
      Really stuck. Any advice appreciated. I’m erring towards selling it on and refunding him if I can get hold of him but don’t want to be the arsehole.
      Sorry if this isn’t the way to do things but I’m really at a loss.
