REBUILDING A PORSCHE 911 GT3RS FROM SCRATCH

[@jaredfitschen9425]

Hey Matt, I’m a luxury body tech in Canada and love what you do here. The panel bond glue that your pops is grinding away panel bond at the 14:00 min ish mark is what we call death dust in the industry and burning all the bond adhesive on the roof is all going to be super high in isocyanates and beyond cancerous.

Engine Builder here, specialize in horizontally opposed engines. The purpose the inner bolts are tighter than the outer bolts is due to the forces applied. The 4 inner bolts have to take the pressure of 2 pistons per 2 bolts where the outside bolts are only taking the pressure of the outward pistons. Never made sense to me either but that's what the engineers told me. Love the content, best wishes.

[@gregedmand9939]

@@OneExhaustedFather When they were reusing the bearing set from the original block, I was worried they would have problems. The tolerances for a race built engine are so tight, that bearing sets have to be fitted to the new block after the crank journals are bored. Even Porsche does not have that degree of perfect mass production, to punch out identical replacement blocks. A new aluminum block is cast, halves torqued together, then line bored. The journals are then measured and the correct bearings are chosen. I'm glad the crew double checked their work and the block codes investigated, before it was too late. Engines with redlines over 8K really don't have room for guesswork. On the bright side, this lesson will prep them for future Porsche rescues.

[@ilovehappyemos]

All the bolts on that engine (cylinder head, connecting rod, main/block) are "Torque-to-yield" so once they're used once, they stretch and can not be used again. That is why the torque spec includes angles, as the angle puts the prescribed stretch on the bolt. I did not see if you had bought fresh ones or not, but if those are the original bolts, their strength is compromised. Would hate to see that incredible engine fail due to re-using the old bolts. Loving the builds!

[@Peter-gi3re]

No, he said he was using new bolts ………..and now he has to get new bolts a second time since he has to remove the heads again to fix the problem he found with the bearing size.

[@frater418]

I worked at BMW for a long time, and for us, it was always like this: with the engines and crankshafts, depending on the engine block, we used a laser tool to automatically read the data. Based on the RMI results, we always used specific bearing shells tailored to the readings. So, it’s possible that the shells you’ve used for this engine block might not be the correct ones, which could cause friction issues that you ideally wouldn’t want. Just for your information.

What I will say as been a mechanic for 50 years now. The Crankshaft Bolts and the Conrod Bolts are streach bolts as are the Cyclinder Head Bolts. Now you are taking it all apart again. I thought that you should have changed those bolts before. But now it's imperative that you now change the cap bolts as they will break! I looked when you said that you have to change the crankshaft main bearings as they are not right. they could easly pick up and spin. then that's buy buy engine.! But got to say that, that is an easy mistake to make. I wounder if you're going to paint is British Racing Green :) Good luck Mat.

[@FreeWheeler554]

I found this: Yes, this looks like a typical tightening sequence and specification for critical engine components, such as cylinder heads, for a Porsche 911 GT3RS. The steps combine torque tightening in stages and angle settings, which is standard practice for high-stress components to evenly distribute tension and prevent deformation. Summary: Initial preload: Start with low torque values (10Nm and 50Nm). Loosening step: Loosening all bolts (360°) helps the components “settle” properly. Gradual torque buildup: Tighten bolts again in smaller steps (4Nm → 12Nm). Angle tightening: Use specific angles (65° for bolts 1-4, 60° for bolts 5-8). Why is it done this way? Gradual loading prevents cracking or warping. Angle tightening ensures a more precise and consistent clamping force than relying on torque alone.

[@MaciusSzwed]

Thats not true! What they should be doing is measuring the elongation of them bolts! 0.15 mm is a normal number to watch for. But most car mechanics dont have that kind of tools, only race engine builders.

[@Kucher99]

Shoutout to Bob with the publicly accessible workshop / tool library. That's a great idea.

[@Sheikob]

21:15 Matt im concerned the old bearings had a lot of oil on them and if some of that oil went on the underside of the bearing. What I've been told is to keep the mating surface of the main bearing and the block 100% clean (spray some brakecleaner and burn off the residues) because if there's a slim layer of oil for example that sits under the bearing then the bearing is sitting that distance above the mating surface and can mess up the clearances.

[@GD7LTD]

Although I do this, and have always heard the same thing. When you torque the rods/mains most of the oil beneath the bearing will be pushed out. I’ve pulled a lot of factory rod/main bearings and most show evidence of oil being beneath them. The reality of them being inside of an engine with oil everywhere 🤷🏼‍♂️

[@duncancarr7822]

I don't know anything at all about engines but I asked ChatGPT about it... sounds like Mat made the right decision: Original Porsche 911 GT3RS has GGGGGGGG and new one has GGGBGBBR - all bearings were added assuming G throughout. Would this be a disaster? ChatGPT said: ChatGPT The scenario you've described indicates that the original Porsche 911 GT3 RS had all main and rod bearings designed as GGGGGGGG (presumably the bearings have consistent material or clearance grades), while the new one uses a mix of GGGBGBBR. If all bearings in the new engine were replaced assuming G throughout, there could indeed be significant consequences depending on the tolerances and material compatibility. Here’s why: Bearings and Tolerance Grades: Bearings are often color-coded or letter-coded to denote slight variations in thickness, material properties, or clearances. These tolerances are critical for maintaining proper oil clearance between the bearing and crankshaft or connecting rods. Consequences of Incorrect Bearing Choices: Tighter Clearances (if the assumed G is thicker than required): This can lead to excessive friction, overheating, and increased wear due to insufficient oil film. Oil flow might be restricted, potentially causing oil starvation to other parts. Looser Clearances (if the assumed G is thinner than required): This might cause knocking, reduced oil pressure, and a higher likelihood of bearing deformation or failure under high stress. Loose clearances could lead to oil leaks and contamination, accelerating wear. Material Differences: If the bearing grades also denote different materials designed to handle specific stress points in the engine, assuming a uniform grade might lead to premature failure in areas subjected to higher loads. Would It Be a Disaster? If the engine has been rebuilt with incorrect bearings: Short-Term Impact: The engine might run, but symptoms like knocking, unusual noises, oil pressure warnings, or overheating might appear early. Long-Term Impact: Catastrophic engine failure is likely. Bearings wear quickly under incorrect conditions, potentially leading to damage to the crankshaft, rods, or other components. How to Mitigate the Risk: Check Clearances: Measure oil clearances for each bearing using tools like plastigauge or micrometers to ensure they are within spec. Cross-Check Codes: Verify the exact bearing grades required for each position based on the service manual or technical documentation. Replace as Needed: If any discrepancies are found, replace the bearings with the correct grades before running the engine. Test and Monitor: After assembly, monitor oil pressure, engine temperature, and noise during the initial run-in period. If the wrong bearings were used, running the engine is highly risky and could lead to an expensive failure. Correcting it before operation would save significant cost and trouble.

The reason they have you torque the bolts and then back them off is to first completely mate and seal the two surfaces together. Backing them off and starting from scratch ensures that you aren't spending any of your torque to seat the two surfaces together. In reality it may only be a couple of ft/lbs difference if you didn't perform this. But with aluminum, heat can warp it pretty easily and the last thing you want to leak oil is this mating surface.

[@PrinceCbass]

I believe the reason the outer head bolts are 5 degrees less is because the first 4 bolts have already started compressing those outer mating surfaces slightly. 5 degrees is likely only a couple of ft/lbs but as with the block, aluminum needs to be much more precisely torqued to eliminate warping under heat cycles. Add to that that the head bolts are "stretch" bolts so "overtightening" them by a few degrees could start to weaken them under higher heat. This reminds me of a funny saying in the mechanic world "it ain't tight until it loosens just a little bit. Then you know it can't get any tighter"

Oh mate! As you were putting that all together, I was shouting at the screen, "CHECK THE MAIN BEARING GAPS, CHECK THE GAPS, PLEASEEE CHECK THE GAPS", but alas, nope ya didn't! You was so focused on the valve clearances ya missed the main bearing gaps, I can see why you missed it, but every block is going to be cast ever so slightly different, so you will always need new main bearings, especially on an engine that splits the block in half like the flat 6. Any new parts where clearance is a major importance, ya gotta make sure the gaps are spot on! I'm glad you decided to strip it back down and gap them properly, because if they seized, that could have grenaded the engine completely and would be, as you say, "A very Bad day!"

It might be easier for you guys to use a countersink bit to remove the rivets, maybe use a slightly bigger than the rivets one. that would save you from using that little sander and then having to pry them.

As some who messes about cars happily rebuilding engines and gearboxes, it is great to see an engine being built that I am never going to see never mind get my hands on.

[@blackraen]

OUCH. Such a small oversight, so much work. That caused me physical pain. At least you already had the practice run.

You guys are nothing short of Brilliant 🧑‍🔧

[@sniper_iye2583]

Matt you have inspired me to become an engineer. Your videos are always extremely funny and extremely entertaining. Thanks for inspiring me and a whole generation .

[@seanryan3837]

Fascinating to watch you both rebuilding that engine. Looking forward to the next one. Chin up you'll get there
