#ProjectMX5 Update + Failure - Mazda MX-5 (Mk1 / Mk2) Forum

Hey guys, a bunch of you who follow me on Instagram will already know that things for Phil are looking bleak…

After a solid 20 hours rebuilding a new head (including lapping all the valves, cleaning all the hydraulic lifters, cleaning and pressure washing the head and inlet manifold two times etc etc), the result is not what I expected.

If you tuned into my Insta live video last night, you’ll have heard that the rebuilt engine now sounds like a diesel, and after extracting a pin out of the side of the head and noticing that no oil was rushing out when throttle was applied, it seems that the oil pump has failed.

This is probably the reason why the original head failed (the camshafts were badly scored), so the entire engine needs to come out of the engine bay (the only way you can access the oil pump).

I will buy a new bottom end soon and will have to invest in an engine crane too. Many of you will think that this is a huge waste of time, but for those of you who really love your cars, you’ll understand the man hours that me and my buddy Gareth (you may recognise him from multiple Project MX-5 videos) are putting in.

Hopefully in a month or so, we’ll have swapped over the bottom end and the oil pump, and here’s hoping that the new, low mileage head is still in OK condition despite being run for a few minutes with too little oil (same goes for the turbo).

Regarding the V6 swap many of you ask about, that’s still pencilled in for summer time. I just want to get out and enjoy Phil because after 6 months of hibernation I really miss him!

No matter how long it takes, we will get Phil running perfectly again and back on YouTube for some shenanigans!
