# 3801527 Longblock Exch | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured long block for the 5.7L-LO/350 cu in. V8 Gen+ with Vortex heads and crank sensor, listed in the reman catalogue as fitting 1996 and newer. Volvo Penta define a Reman long block as a cylinder block assembly with pistons, connecting rods, crankshaft, camshaft, cylinder heads, rocker mechanism, oil pan and valve cover, and no further. It weighs 210.92 kg, the lightest of the ten long blocks here, covers 45 applications on V-series engines and consolidates eight earlier numbers, 3801522, 3801528, 3801523, 3801544, 3801409, 3801656, 3801622 and 3801410, all catalogued as longblock engines. This unit is supplied on an exchange basis: core deposit 3804527 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

## ⚙️ Key Features

-   5.7L-LO/350 cu in. V8 Gen+, fits 1996 and newer
-   Vortex heads with crank sensor
-   Contains block, pistons, connecting rods, crankshaft, camshaft, cylinder heads, rocker mechanism, oil pan and valve cover
-   210.92 kg, 45 V-series applications
-   Consolidates eight earlier part numbers

## 🔌 Function

Supplies the block, crankshaft, pistons, camshaft, cylinder heads and rocker gear as one remanufactured assembly, replacing the core of a worn or damaged engine without a full new unit.

## ⚠️ Common Signs of Failure

-   Low or uneven compression across the cylinders
-   Heavy crankcase blow-by
-   Knock or rumble from the bottom end
-   Oil pressure below specification when hot
-   Coolant in the oil or gas in the coolant

## 🛠️ Service Notes

-   Eight superseded numbers resolve to this one, so an old quotation under any of them is still current
-   Long block 3801529 is only 5.4 kg away but is the high-output 5.7L-HO package for 1999 and newer, so the output rating is what decides
-   Transfer or renew the ancillaries the long block does not include, and return the core once the engine is running again
