Nissan VQ-Series Rebuild
A 24-valve V6 pulled, opened, and gone through completely — timing components, gaskets, and seals replaced before careful reassembly.

The Mechanic
One set of hands. Every job, start to finish.
I'm Brandon Trombley, owner and sole mechanic at Under Pressure. Over 12+ years I've gone from daily-driver maintenance to full engine-out rebuilds and forced-induction builds.
When you call, you get me — not a service writer, not an apprentice. I pull up to your driveway, you watch the work happen, and you pay a fair price with zero shop overhead baked in.
Honest work. Fair pricing. Convenience. There's no job too big or too small.

How it works.
Booking a mobile mechanic should be the easy part. Here's the whole process.
01
Tell us what's wrong
Call, text, or send the form. Describe the symptoms and where the vehicle is. We'll give you a straight read on what's likely going on.
02
Get a clear estimate
You get an honest, itemized estimate before any wrench turns — parts and labor, no surprises, no shop-overhead padding.
03
We come to you
We show up at your driveway, lot, or workplace and do the job on site. You watch the work and drive away the same day when possible.
Ready When You Are
Skip the tow. Keep the keys.
Most repairs don't need a shop — they need the right person to show up. Tell us what's going on and we'll get you scheduled, usually within 24 hours.
