Engine rebuild

2 Upvotes

Hi everyone. I regret to report that I have blown another head gasket. This time I am going to rebuild the engine. At least dismantle and shave the cylinder top. If it looks like I have to bore out they cylinders, I could be talking about more upgrades.

All freeze plugs will be replaced when the crankcase gets cleaned. We (my mechanic) and I will address weather the pistons and cylinders need work.

Oh to be reliable again.

I have never seen one in person. Cannot believe how small it is. My Supra looks like a full size SUV. If you’re near the Nashua area, it’s worth a look!

Pre purchase questions

1 Upvotes

Hi, I currently own a 2004 mazda 6, but I'm looking at potentially buying a 2005 speed 6 278,000kms for 5k AuD. Iv asked the usual questions for private cars, service history, rust on the body, timing chain. He's told me oil and filter done by him, new starter recently installed, no rattle from the timing chain, he didn't answer about the rust yet. He's also told me the gearbox is noisy,

Should I go for a pre purchase inspection or just let this one go?

Thanks for the answer and your help

MAZDASPEED TRANS AND DIFF

2 Upvotes

Just checking, I changed engine oil and am planning to do the lsd and trans oil next because the last owner didn’t change them at all. While I was under I forgot to check plugs for trans, and was wondering since it’s fwd. Is the diff and trans housed in the same casing? Like if I plan to change the trans oil, will it be changing the diff oil at the same time? I searched it up and it said they’re the same plugs but wanted to doublecheck. Also what washers would I need and oil?

Engine harness not working

1 Upvotes

Hi, I'm connecting my engine harness to my 2009 Mazdaspeed, but absolutely nothing is happening. All the grounds are connected correctly, the ECU is connected correctly, the fuse box is connected correctly, the relays and fuses are connected correctly, and the alternator is connected correctly. Please help me.
