I’m looking at a V70R, and heard the phrase “shimmed block” because of a known issue. And the fact that I now know what it means, and can see the cylinders divided in between, it all gone through the toilet!! No way I’m getting this car!! 🤣 🤣 🤣 Next car I get, closed deck all the way!!
How common are these cylinders to crack? I really want to get my hands on a ‘05 S60R within the next 2-3 years, and just want to know what to be cautios about when it comes to maintenance and stuff like that? Let’s say I go for a stage 1 tune pushing 354hp / 493 nm torque. Will I have to worry about shimming the block?
About 3 in 10. Alot of Europeans swaped to the regular 2.5t engine and tune it since the cylinder walls don't have that gap. But it's all dependent on how many times and how often the owner pushes the car.
Why do you have the extra length on the ends protruding into the water passage? Could you give the measurement of the length of the shim and not just the thickness? How did you fabricate the metal for the shim and what is it made out of?
I just found out that theres something called "Shimming an engine" but what is the point of this?😅 I suppose the cracks where he adds the shim are from factory, so is it to make the block more stable from combustion vibration or, whats the point?😅 And if it IS from factory, then why the cracks?😅
Is this an issue with the NA engines at all? The T4 makes around 300hp while the NA versions are below 200hp. While they all use the same block right? Well, no surprise the open deck block with expansion gaps in between the cylinders has its limits.
Yes, I did tap that outer edge a bit. I was looking at the camera and not what I was doing. Fortunately, it's an inconsequential spot because it doesn't aide in the sealing of the cylinder to the head. Obviously it was frustrating but I didn't notice it until after I had made the video 🤷♂️🤣
@@swedesource6785 I reckon it was the ball bearing that caught it there, I have a B5234T4 and I have just started to see coolant in my oil, only a little hardly anything missing from the expansion tank at all but the oil has discoloured on the dipstick a little, once I started it from cold a couple of months ago and it had a slight misfire, it went after 30 seconds or so and has not done it since, I'm hoping its not the liner issue I didn't think this was common on the 2.3 engine?
if i did go buy the sheet metal shims, i know their thickness but about how long would these be? and do they need to go lower into the block or is what you have sufficient enough?
I'm trying to understand a statement you made on another comment. Did you shim the engine after the cylinder cracked, and then got another 100000k miles out of it? Ie: Will shims fix an already cracked cylinder?
I've never done that, no. But I've heard of people successfully doing that. Obviously, I'm sure it highly depends on how bad the crack is. Basically, I've seen people stuff JB weld into the slot with a shim and just call it a day. Sounds like too much work for a "maybe".
The small gaps between the cylinders allows for the cylinder walls to expand, and when that happens they crack. The middle two cylinders are particularly prone to expanding and cracking. This problem is primarily on the B5254T4 engine out of the S60R/V70R because it has the thinnest cylinder liners out of the 5 cylinder engines installed in Volvos. Thin cylinder liners, combined with the highest horsepower and torque output of any factory 5 cylinder means bad news. Shimming the gap with snug pieces prevents the expansion of the cylinder liner. So far, I personally haven't heard of anyone with a shimmed block getting a crack in their cylinder liner. It's not a perfect solution, but it's the most cost-effective one. I personally owned an S60R which ended up having two engines with cracked liners, and since shimming I continued for another 100k miles without another cracking issue.
@@swedesource6785 does that shims prevent cracked liners? thas is problem on fosus rs mk2 305hp with B5254T3 engine too? it is posible to re-sleeved it?
@@swedesource6785 I'm trying to understand your statement. Did you shim the engine after the cylinder cracked, and then got another 100000k miles out of it?
@@RepsolRC211V The shims help prevent the cylinders from expanding which is what causes them to crack, so yes this will help prevent the similar issues with the cylinder liners. Ford owned Volvo in the mid 00's and the Mk2 Focus RS used a variant of this engine so it's highly likely this would be a solve there too.
Yes we sell the shims on our website. There isn't really an answer about what it can handle. That highly depends on your tune, fueling, and many other factors. I'd say it's safe to say that it can at least handle stock horsepower 🤣 I personally ran 20 PSI reliably on the stock internals with shims.
Nice video but while shimming can strengthen the engine structure, it could have unintended consequences such as hindering coolant flow or restricting cylinder sleeve expansion. cylinder sleeve gap is there for a reason. These engines have been designed by engineers with qualifications and years of experience. Is there concrete statistical evidence to prove that shims actually fix the problem? What if multiple variables are contributing to the problem? Poor tuning, poorly maintained cooling system. Excessive revving, poorly maintained lubrication system...etc.
If there were actually unintended consequences, people would be talking about it. But they aren't. If the engineers knew what they were doing, cylinders wouldn't be cracking in the first place. The best motors out there are completely closed deck. Honda guys fill their blocks. I've personally been selling shims for years, and not a single person has came back saying their motor cracked.
@@JMT1227 Thanks for taking time to respond. I had to be honest and open with my question because I drive a stage 2 tuned 2010 Focus ST. It doesn't have shims however, I don't do track driving. Still a concern though.
hahha, nice mark you left on the cylinder sleeve at 4:50. Then went on to say how you don't want that. That must have hurt.
He didn't even see it I beleave 😂
@@ehmjauhh5495 Sadly, I did see it.. I hate myself for it 🤣 but thankfully it's an inconsequential area.
Does the shims being so long, extending that far into the coolant passages, partly blocking them right off, restrict coolant flow in any way?
it's got 2 I'd try to bend them a little more at the end so that they flow better but that might cause a problem for whatever reason
Can you make the shims shorter or less in width to fit better?

@@Sr.-Mizz Every whiteblock engine has the slot between the liners. Making them hold a lot of power is all about tune.

I think the shims are too long and it can affect on cooling, why didn't you cut them to have 2-4mm for each side?
A steel shim in an aluminum block? Wouldn't the different thermal expansion rates cause issues?
I would believe the space between the cylinders was Split for a reason
Vast majority of aluminum block engines have steel sleeve cylinder liners. You can see it in the video.

Can you shim the block with it still in the car?
This is a good question
@@dirtypeach Yes
How do you know that the shims will stay in place and not slide down over time?
The slit is only at the top of the cylinder it doesn't go any deeper
The slot is only nearly as deep as the shim is wide.
It just taps in that easy? No cutting or anything like that?
Is this an issue with the NA engines at all? The T4 makes around 300hp while the NA versions are below 200hp. While they all use the same block right?
Well, no surprise the open deck block with expansion gaps in between the cylinders has its limits.
Do you need to pull the engine to do this or can it be done in car? Early stages looking at a T5 V70R and a S60R. Not sure which way I’ll go
You can do it with the engine in the vehicle no problem.
4:50 Engine block was damaged little bit after tapping.

The shims do not need to go lower, the problem area is at the top of the cylinder. You can save a lot of time by purchasing our shims.

Thanks for the reply. 🙂🇦🇺
Nice video, whats the purpose and bad side of shimming the engine block?
If those gaps are not shimmed, the cylinder walls will crack, causing catastrophic engine damage. Regardless if the car is tuned or bone stock
How long does this take to do? And what are the costs? How much would you charge? Thanks!
Message me directly through the SwedeSource Facebook or IG account.
My machinist didnt charge me for this since he didnt have to machine anything.

What Is the shims function on an engine?
reinforce the cylinder walls so they dont crack under pressure
How much engine will take after this operation? Can I buy this shims from you?

What did you use to clean the cylinders
Scotch pads and elbow grease. Tape off the deck and you can also use a wire brush for heavy buildup, just bring the piston to TDC while doing this.
this is kind of like asmr
Whats asmr?
Good info.. Thanks.
